I have installed TeamViewer on linux mint 20:1. TeamViewer opens in 30 seconds
I have the same issue, which cannot be necessarily solved by a reinstall. As I did one new nothing changed. Reinstalled TeamViewer and that would not help either. I am on Mint 20.1 now. Unfortunately could not find any evidence in logs or "taks manager" that the app is facing some issue. It just starts as a dormant process and after approx. 20-30 seconds it pops open and it seems to work from there, but is very very annoying. Wish support would do something about it.
Same problem. My PC need 35 sec. for booting the Teamviewer service.
