Initial set-up seemed to go well. However, after restarting Joplin and then hitting the Backstage icon, the QR Code dialogue box does not appear. The only box shown is the one summarising the connected device.
When entering the server details manually, I'm able to access the server's web page. However, as it requests me to scan the QR code or enter a valid OTP, I'm unable to connect.
Joplin 2.9.17 running on Mac OS Big Sur
