Problem with newly created sub-folder

[Energise]

Using Tb v 60.9.1 (Yes, I appreciate this is old version but have reasons to keep to this version just now)
on Windows 10 v 22H2 (64-bit)

I have just created a new sub-folder on Inbox (gmail.com a/c) which I have done previously. However, this time, I'm unable to move any emails into it, nor can I delete it. I've tried creating a Filter, to see if that might help, but (filtered) emails only arrive in my Inbox, not filtered.

I've tried to delete it, as it's clearly of no use, but I can't delete it either.

Please can someone help either to have the sub-folder working or to delete it?

Many thanks

Try logging into the web site with a browser and removing the folder or label.

Remember to exit Thunderbird before logging into the web site.

If you remove the folder on the hard drive, then I believe the app will recreate the folder.

How is the account set up in Thunderbird, as POP or IMAP? Find out using menu path Tools->Account Settings->Server Settings->Server Type at the top right of the dialogue.
Have you tried shutting down Thunderbird and restarting it?

Thanks morat
I've just tried but gmail webmail is not opening just now. I'll try again shortly.
I appreciate your quick response. I'll report back, should this not work. Otherwise, will leave you undisturbed Again, thanks

I've been to the web mail site and discovered there were emails in the folder. So, the sub-folder is working now. Strange. Maybe it just needed Tb to be close and re-opened, or something.
However, more learnt - When/if I have further issues, I'll close and re-open Tb, check webmail etc, before posting an issue
Thanks again

Thanks very much
I think posts must have been sent with only slight time difference so you may have read my response already
As you will see, it's sorted now.
Thanks again
