Someone in the forum told me that an 'insider' in either FB or Apple told them to open up the Messenger app. And, while that was open to then login to my Facebook app...and it worked!!! I'd love to know if it works for you.

That is the current workaround until Meta provides an update to fix the problem with Facebook. They have a poor track record when it comes to bug fixes especially those found on the iPad.

Do you use VPN? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile. If that fixes it, you can try reinstalling VPN.

But keep in mind that social networking apps hate VPN, and frequently will block VPN connections. SnapChat in particular will ban you for 3 months for using VPN, and permanently if you do it again.

I got a new iphone today. I was able to get into Messenger today, but I can't access the Facebook app. It is almost blacked out on the screen. I can't call it up at all. I can't delete it. I guess I will try powering down and back up again.

Instead try deleting the app and reinstalling.

Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile. If that fixes it, you can try reinstalling VPN. Any time you upgrade hardware you should any network apps and reinstall them so they can configure to the new networking.

However there have been many reports (3 pages in this thread alone) of problems with Facebook, which is a very buggy app,

Hello all! I was able to restore my Facebook after the latest update and getting a new phone. I opened Messenger as others have said here, but that didn't help.

My facebook icon was dark and non-responsive. I pressed and held it, and a menu came up. I chose to give downloading top priority. After about three minutes, it was there! So try this!

I was able to get Facebook to launch after the update by holding down the icon (it was dark and non-responsive). A menu came up and I selected Prioritize Download. Within about three minutes it had loaded and all is well.

Yes, EVERYONE else who uses Facebook; it is a major bug in Facebook. However, there is a workaround posted earlier in this thread that you must have missed in reviewing the thread before posting. Here is a link to it→Facebook won't launch after iOS 18 update - Apple Community

OK, let’s try one older solution: Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile. If that fixes it, you can try reinstalling VPN.

Facebook not working after update on my iphone

Delete and re-install the Facebook app. If that doesn't help, contact Facebook/Meta support.

Meanwhile, you should be able to access FB through a browser.

Facebook just had another update today to go along with the 12 they have had in the last month. They have also had the beta version of iOS 18 for 3 months to make sure their app will work correctly. If you are experiencing any problems with the Facebook app, then contact them using their Help Center.

The only thing that you can do is delete/reinstall or restart your device, other than that, it will be Facebook that will have to resolve any problems.

Got the fix from a genius at apple support. Off load or delete the Facebook app and the messenger app. Then upload the messenger app only. Open it. Then upload the Facebook app, login and you should be in business.

Did you follow the directions carefully?

• FULLY delete Messenger (don’t just remove it from the Home screen)
• FULLY delete Facebook (don’t just remove it from the Home screen)
• Go to the App Store and download Messenger ONLY
• Log in to Messenger
• Go to the App Store and download Facebook
• Log in to Facebook

Make sure you have the most recent Facebook app update. Otherwise contact the developer to report issues. You can also try deleting the app and reinstalling or even try restarting your device. I have had no issues with the app in iOS 18 or iPadOS 18.

how to launch facebook after ios 18 update?

Delete Facebook, then redownload from the App Store. If that does not work, contact Meta for assistance with their app.

Perhaps a long shot, but a very common cause of communication failures:

Do you use VPN? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile.
