Subtasks don't repeat (randomly)

Since the new sync update, I have a problem with my repetitive tasks. How to reproduce (Android, Samsung Galaxy): - I have a task with 8 subtasks on last Thursday. The task should repeat daily. - I mark the task as done. - The task is repeated on Friday. However, with only 2 subtasks. I have tried this several times and the amount of subtasks is different each time, ranging from 0 to 2 (out of the original 8). My developer boyfriend saya it sounds like it's a sync timing issue where once the head task is synced, the sub tasks stop syncing
