Hi @BennyBoy
Welcome to Q&A forum ~
As OneDrive tag focuses on general synchronization issues of OneDrive desktop client, but your issue is related to OneDrive on mobile device, which is not supported on Q&A fourm at current time.
To help you better, I would suggest you post a new thread on Microsoft Community.
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.
Thanks for your understanding.
