[Raspberry] Anyone able to use older versions of TV in Raspberry OS(raspbian)?

Hey everyone hope somebody has seen this problem before.

I have a commercial license for Teamviewer 12 and I have been using it on Raspberry Pi devices on my company for years.

I reacently bought a Raspberry 4 and when installing the raspbian host for teamviewer I was not able to connect since I had an old version of Teamviewer (version 12) and the only availabe version on TV website is TV15 (for raspberry).

I figured I needed the old installer which is not in the website but luckily I had an old TV12 (teamviewer-host_12.1.83885_armhf.deb) installer. I installed this client for raspberry and it did not work. The problem is that even when im sure I have an internet connection it looks like if I didnt have one, it doesnt show ID or pass and I also cant click on settings.

Note: I have not tried TV for linux since i thought it was a different version for Raspberry since it uses ARM.

Any ideas?

Thanks!
