TeamViewer automatically logging out, even with "keep me logged in" selected

Looks like this was an issue in the past and it's happening again. On at least 2 machines that i know of, TeamViewer has logged itself out (multiple times) even after making sure that I've selected to keep that device logged in. The systems have not rebooted. This makes trying to connect to a remote device, well, impossible if it's supposed to be logged in perpetually but the software is logging itself out.

I'm running version: 15.61.4.

I saw in a previous thread this was an issue in 13.2. Is the issue back in 15.6?
