Hi Kevin, the keep on device - free up space trick seems to fix the issue. Thanks.
Currently trialing this with a user to see if this is actually a long term fix. Will report back if not.

Update on this - the fix as described by kevinmckeown8 above seems to have done the trick.

Thanks so much for sharing
