After following the QR process for my email accounts import into Thunderbird for Android (importing from Thunderbird for Windows) only one account is showing all folders. Gmail and Outlook and Yahoo are only showing Outbox, while my Apple email is showing all folders, immediately after importing, none were showing. A full day later, only Apple shows and all others are still showing only Outbox. Apart from removing the app and trying again, any thoughts on why this is happenning?
