They look to have changed their signing key without handling that via apt or bothering to tell us.

You can possibly fix it in the interim by getting the key you're missing using something like

sudo gpg --no-default-keyring --keyring /usr/share/keyrings/teamviewer-new-keyring.gpg --keyserver keyserver.ubuntu.com --recv EF9DBDC73B7D1A07

and then pointing your apt repository entry at that key by changing the signed-by (or replacing the existing key)

Since they have disabled the links to the repository instructions sorting a proper fix for the definition might be non-trivial.

Ah - they seem to be making a DIY repo management/maintenance function into teamviewer so you'll get a prompt on install where you can decide to adopt their whatever-it-is helpfulness

Meanwhile I have a working fix in the pipeline for our definition.

FYI : they install a keyring with extra keys - possibly legit for resilience, rotation support and/or different signatures for different release streams.
