Just upgraded a 9th gen iPad (64GB) to 26.3.1 - very tedious because the iCloud Sync function and app offload don't function correctly to reduce local storage usage enough to make room for the upgrade. In particular, if least-recently-used apps are offloaded, iCloud photos actually increases its usage. The only alternative seemed to be to turn off iCloud Photos and manually delete local iPad photos.
The reason that I have the iPad is that I like to use it to display photos in my medium-sized (< 500GB) iCloud Photos library. (iCloud Photos and Photos on a Mini hold the library). The iPad is the right size to show people photo albums. (iPad, Mini, and iPhone are all 26.3 at this point.)
This has not been a problem on a 128GB iPhone SE2. There, the storage manage/iCloud cache functionality ("optimize storage") works as expected, which is to say, the Photos cache on the iPhone grows and shrinks as necessary without my doing anything. So, I wonder why the "optimize storage" cache function won't behave properly on the similar iPad. Bug or feature, I couldn't say, but, it would be nice if the iPad worked like the iPhone.
