How to Download older version of apps
i factory reseted my iphone x which is now on ios 16.7.12 which is that lastest update to support the iphone x and i can't download some apps because it requires ios 17 any idea what to do?
You're out of luck. Unless the developer offers an older version then the app is not available. Many apps that rely upon higher security will only be available for the latest two iOS versions. Owners of older equipment are a diminishing percentage of users and it probably isn't worth developing for those, plus their older equipment may not be able to run newer security features.
