Current version of teamviewer does not allow pre-login access on linux.
Community disccsion in linux chats shows that this capability was broken in the upgrade from 15.9.5 to the current version.
I'm looking for the .deb of the 15.9.5 version, and the website "previous version" options only give the last released versions of the major numbers , e.g. 11, 12, 14, etc...
In general, it's important that all versions be available for precisely this reason.... the developers can break any number of features, and unless it is instantly patched, there needs to be a rollback capability for users that rely on this software.
Please provide a link for the 15.9.5 version.
