Hi,
I recently updated to the latest version and now after quitting TeamViewer and re-opening it, I get logged out despite having checked the "stay logged in" box. I tried reinstalling, clearing configuration settings, logging out and back in multiple times…
Downgraded to v15.54.5 and now it works again so there likely is some kind of regression.
OS: macOS 14.6.1
Let me know if you need more information.
