Giving revoked user access again

I am having issues restoring a revoked users access.

Once revoked, the user just gets “Connecting” on their Zero Trust WARP all (in Windows). Rebooting doesn’t help and the Re-authenticate button from Preferences just says “Error: Please enable WARP”. I may need to re-enable their access but the only way to do this seems to be to uninstall and re-install WARP. Is there an easier way?

Thanks
