Says Version 13.2 requires iOS 10.3 or later on compatibility which has been the minimum since version 10.0

iOS 11 is the minimum for to fully use some features.

My iPad Pro is updated to 12.1 but Apple repressive will not allow updated app or features I’ve tried this on numerous occasions but I don’t have the best experience and limited to my mobile devices for now. Laptop is being repaired . No images but I’ve been using Apple products for six years and never had any issues until most recent update. Now I have sincerely considered getting rid of all of them , even though I’ve just spent at 1200$ on the Xs max. I’m learning more though . I have contacted Apple support with interference from support workers, Yet Apple support response is that Apple would not interfere with my personal life or private email although it has been done and even posted my router information in cloud keychain without any permission. .Some of it has stopped but still it’s getting harder and more complicated continuity. I hope that when I can sync my laptop it get a lot better and updated easily.
