Every time an auto sync is run, it is updating all 2077 contacts despite nothing having changed. Is this a bug, or is there some way to skip contacts that are static? I saw some reports of downgrading back to 4.1.33 as a fix, is this the recommended resolution? Photo attached. Thank you

Just to provide an update, I downgraded to 4.1.33 as recommended by another user and the initial sync did run shockingly fast compared to 4.2.1. However, I started a second manual sync just to ensure everything was working properly and it started syncing very slowly again. Please see attached for a photo. I have no idea how to fix this, so any input would be greatly appreciated. Thank you

I have the same issue. It now sync's all contacts on every sync, even though no change to the contact was made.
Additionally, I have 253 Google contacts, yet it showed only synced 68 of the 253. As a test I updated all 253 Google contacts by opening each and making a minor change with save. After that it synced 250 of 253.
The next day I went to see if I could identify what 3 are missing from the sync and it now shows only 67 are being synced.
Is there a logging mode I can set to help identify why it continues to sync 67 of 253 when no change is made to that contact.

Example: 2025-10-17 06:26:26 | Information | Sync complete. Synced: 67 out of 253. Deleted: 0. Skipped: 0. Errors: 0.
