Automatic syncing no longer works after Letterboxd import

Hello, I’m VIP level for several years. I’ve sent in several support tickets but have yet to receive any responses. Hoping someone will be able to help me here.

Earlier this week, I imported my Letterboxd data, since I’d like Trakt to be my sole app for tracking and rating what I watch.

Ever since that import, though, nothing has synced automatically. It just stopped working at the time I did the import.

This seems to be the case on both the app and the Trakt.tv website.

Anybody have any ideas on how I can fix this?
