Hi When I create a new subfolder (right click on parent, select new subfolder) the new subfolder does not display in the tree on the left hand pane. The folder has been created - if I go to the Subscribe option I can see it there, ticked. If I log into my Gmail account on the web page I can see it there. If I shut down TB and restart it, it appears. I have tried the Subscribe option detailed here: https://support.mozilla.org/en-US/questions/1058346 but no change. and looked at the Profile fix here: https://support.mozilla.org/en-US/questions/987821 but I do not have a ImapMail folder in my Profile. TB version 91.9.1 (64-bit) Running on Linux Mint 20.3 Una In the previous version of TB this worked OK, but I can't say for sure if this started happening immediately after the upgrade or not. Any suggestions gratefully received!
