On my Apple M4 Pro, Mac OS 15.5 with installed Cursor arm 0.50.5. I am logged with Pro account.
I cannot initiate any chat. When I write anything with or without context and click Shift+Enter or the arrow, the chat appears for <1s and disappears. Down below, the “Cursor Tab” is crossed and it says upon hovering “Requires Pro (Custom model)”. However, when I follow the link it leads to my properly set and logged account with Pro.
