Sometimes I get `HTTP Error 401: Unauthorized` when trying to export to YouTube

Thanks for adding Youtube export. Very handy.
Though sometimes, I get a status 401 error. Disconnecting & re-connecting to Youtube fixes it. Here’s the logs for it:

Thanks for the detailed report and logs - they were very helpful in tracking this down.

The root cause: Google OAuth2 access tokens expire after 1 hour. If you connected to YouTube and then waited a while before exporting, the stored token would be stale by the time the upload started. The app wasn't checking expiry before using it, so it would try the expired token, get a 401, and give up. Disconnecting and reconnecting issued a fresh token, which is why that workaround worked.

This is now fixed in v0.1.124. The app now stores the token expiry time and proactively refreshes the access token before starting an export if it's expired or close to expiring - so you shouldn't need to manually reconnect any more.
