Missing sent folder in Thunderbird gmail account.
Sent folder does not appear in gmail account. "Place a copy of the sent messages in the sent folder" is checked. A sent folder is listed under gmail profile but does not appear when Thunderbird is started.

Since gmail automatically copies sent messages to the Sent Mail folder, uncheck 'Place a copy in' in the Copies & Folders settings, and subscribe to Sent Mail (right-click the account in the Folder Pane, Subscribe...).
When I right-click the gmail account in the folder pane, there is no "Subscribe..." option.
If Subscribe isn't available, the account is POP, so the Sent folder won't appear until after you send the first message.
