Disappearing apps on my new iPad mini and my iPhone 16 Pro Max😱

My apps just up and leave the building on my new iPad Mini and my iPhone 16 Pro Max. I always find them in the app library ~I really dislike the app library very much! I really hate it when I go look for an app that I need and I have found out that the library ate it!

So then I have to go and put them back on the desktop pages and it’s very annoying. Why is it doing that? Also I want to delete the App Library forever and I know we can’t do that but I can move it off of my phone and put it somewhere right?

also, I have another question on my iPad mini here. I think it’s the A17 but I can’t go look in settings because then I’ll lose the screen and it’s not on my iPhone settings. I thought it was. But the question is how do I turn up the volume on my iPhone and iPad I have troubleshoot I have googled it as Google is our friend, I have done everything possible and it’s not getting any louder😞
