It only updates like 1 or 2 games from my list and the rest returns as a failed entry. I've checked the error message it gives and they're all 429's "Too Many Requests".
I mean I do use Discord and we could chat over that if you really want to, but I prefer not to publish my account and open DMs to strangers. SourceHut tickets, GitHub issues, pull requests, itch.io forums, email, all that should be enough for Mitch discussion IMO.
