App is impossible to use. Slow to switch channels, edit posts or do anything. Save button is often missing in edit mode if you edit too soon before it fully loads. Is the app going to be fixed? Update: Updated server to 8.0.1 and no improvement to the app. This has gone on long enough without a fix. This should be a critical issue and fixed immediately.

Currently not able to open an image posted by another user. Tapping the image doesn't do anything. No error message or anything. Server version 7.1.5. Just a normal png screen capture and it isn't consistent. Maybe related to network quality? If so something indicating it's trying would be helpful. Edit: I'll ask about the server upgrade. Is 7.8 the latest?

Hi Sidney, to eliminate any server side issues, would your system admin be open to upgrading the server to a more recent version, such as 7.8 which is the latest ESR version?

Rarely gives notifications, conversations don't update reliably so if i send a message on my phone it won't appear on a computer. file transfer is very limited and absolutely no video sharing capability. I've had other issues but I can't even remember them all. Lately its started just logging me out and ejecting me from the server, so now I'm definitely not getting any messages, so that's been fun. (The name is also super cumbersome but that's neither here nor there. )
