The only reason I can think of is for more on device ai. LLMs like ChatGPT are extremely greedy when it comes down to RAM. There are some optimizations that squeeze them into a smaller memory footprint at the expense of accuracy/capability. Even some of the best phones out there today are barely capable of running a stripped down generative ai. When they do, the output is nowhere near as good as when it is run in an uncompressed mode on a server.

The back gesture is fine until it takes me out of an app. I hate that. Sometimes I trigger it unintentionally because I’m trying to swipe in an app but the system picks it up instead.

As long as the app is storing the auth token received from the lemmy instance securely it makes no difference whether you login once or multiple times.

That back gesture on android is a system level gesture. On iOS it is an app level thing. If it doesn’t work it’s because the app developer was lazy when they made their own custom navigation controller. File bugs and leave low rating reviews.
