Opening new chat window lost the context of previous communication, so it’s not an option.

Seeing same issue after upgrade, context of the google drive connection had previously failed in this chat, and thus is now throwing error permanently in chat. Like buzzdroid says, ■■■■■ to lose context

Describe the Bug

Yesterday, I noticed a new thing: every so often when I attempted to send a prompt, it should show as sent to AI (moving to the top) but then a few seconds later, it would be back at the bottom in the prompt entry area as if I didn’t click the send button. I clicked the send button a second time and it would send most of the time. Sometimes it would take a 3rd attempt but it always worked at some point.

Today, nothing is working! As a hack developer, I really need AI because I cannot do the updates without it
 I just don’t have the skills. Today - I’m completely stuck and not getting ANY work done right now.

Each prompt only returns this:
