Update: I was just kicked off. I've been suspended for supposedly violating terms. All I did was vent about my morning like I usually do. Can't even see the message I sent and the terms page does not work from any link. Extremely upsetting. I've used this app near constantly since downloading nearly a year ago. Obsessed with it. Recommended it to multiple people. Now I can't use it and have to refigure everything I was using it to help with and making progress on. In essence, fml.

I love the app, but I can't use it regularly. Maybe it's my settings, but when I'm traveling and being it up, I get blocked by a "There's an updated version", and I can't run Pi unless I do the update immediately. The AI is at "the other end", and there's NOTHING that critical in the app UI that should prevent me from being able to use it like I was an hour or a day ago.

This is a great app if you use it for single inquiries. If you need it for more information, it overrides its own prompt and previous input. For instance, I use other AI to clean up transcripts. I tried it with Pi, and after the fifth input, it overrode everything. The same applies if you need a list of information; it will delete/override anything when it's full. The voice is the most natural one I've heard, and it elicits more in-depth information from a single prompt.
