Messenger app won’t l start on iPad

There are many reports of issues with Messenger. Many users also report that deleting both the FaceBook and Messenger Apps from the iPad, prior to restarting and reinstalling the Apps, will successfully resolve the problem. Perhaps this will also work for you - but note that the workaround is very specific in both actions and sequence.

Delete apps on your iPhone, iPad, and iPod touch - Apple Support

Force restart iPad - Apple Support

After deleting both Apps and restarting the iPad, install and launch Messenger App first - and then reinstall the FaceBook App:

• Messenger

• FaceBook

https://apps.apple.com/gb/app/facebook/id284882215

Messenger is a Facebook App. They provide support. Start here:

All we can do here is say your iPad 2 (I assume that is the one causing the problem) is, per Facebook's web site, still capable of running Messenger.
