My biggest peeve with iOS or iPadOS is that if you sync photos or SMS with your iPad, you will eventually run out of storage. I don't know why Apple doesn't do a "rolling" storage for these apps, it feels so broken. I'm never buying another iPad if they don't fix this, I'll pay their competitors instead who sanely allow you to decide which photos to download for offline viewing, and which ones to keep. I will always have way more storage on my phone than my tablet.

There will also be a time where my iCloud Photos storage will surpass the available physical storage Apple gives you for your phone, so I don't understand this weak design.

Worse is the Messages app, which insists on downloading every gif, photo and video I share to my iPad as well, as if I need them available for offline use all the time, no Apple, if I needed to see any of it, I would download them manually.

iOS and iPad OS need to be smarter about their Photos and Messaging apps, they're really dumb. What's the point of iCloud if it forces everything downstream when I'm not asking for it.
