Hi @BednarPe94, thanks for reporting this and for the detailed environment info.

We're aware of an issue where QR-code login can intermittently fail or log the user into the wrong endpoint, and we've been able to reproduce it on our side. The fix is planned for next releases.

Hi @deaflynx,

thank you for the answer.

Is it mobile app problem or platform problem?
What is the best solution or workaround for this issue? Not updating the mobile app and stay on 1.8.0 version?

Best regards.

@BednarPe94,

This is app problem and it exists also in 1.8.0 version if I am not mistaken. Have you tried to refresh the page with QR code (home page) and rescan?
