It is very frustrating to type in a long, complicated query and hit enter only to be met with the login screen.
This happens if PreGPT has been open in a browser tab for some time, and the login times out. You are training users to either not trust PreGPT or to treat it like a groggy companion…
My suggestion “PreGPT should check logged in status PRIOR to allowing user to type in query.” is only to illustrate the problem. Your devs may choose another solution, I can think of several.
