I sent a copy of the invalid signature to the help department and this was their reply:
According to the Terminal output you've provided, you are experiencing issues with some invalid signatures of other software/packages on your device:
The following signatures were invalid: EXPKEYSIG 0FAD31CA8719FCE4 home:stevenpusser OBS Project
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error:
http://download.opensuse.org/reposit.../xUbuntu_20.04 InRelease: The following signatures were invalid: EXPKEYSIG 0FAD31CA8719FCE4 home:stevenpusser OBS Project <home:stevenpusser@build.opensuse.org>
That said, this is not an issue with our Linux app beta directly and you should check your repositories/signatures in order to resolve your issue. I suggest you check the documentation/forums of your Linux distro for more information regarding this matter. Alternatively, you can try the other connection methods:

Where do I go from here???
