Hi, I think this has happened since a recent Thunderbird Update but cannot say for sure. I keep receiving the same single email from 21/06/19, 11.18am every time I press the Get Messages button. No new emails at all are getting through even though I know I have received them (phone shows me). The wifes and a friends email account is also on the Thunderbird app and their new emails are being received. It's just my emails not getting through. To date this email has been received over 200 times. Please help!
