Changes not syncing

When studying my flashcards, I am getting a “Rejected by server” with a notification stating that the change didn’t sync. This has been happening with the latest updates and it seems to affect the study material for mastery level since it doesn’t sync up my answer and my grading.

One note I have, it seems to be happening when clicking the parent card’s “Xdue" where x is how many flashcards are due today. If you go into the parent card, and select the Xdue number, it seems to sync correctly.
