• Only RetroArch bugs should be filed here. Not core bugs or game bugs
• This is not a forum or a help section, this is strictly developer oriented

Description

Coud sync is set up on webdav server on TVOS and and MacOS.
Sync on TVOS is ok, no error during synchronisation.

Actual behavior

Synchronisation fails and the saves on MacOS are not synced with CloudSync.

Steps to reproduce the bug

1. Playing on GoldenAxe Warrior on TVOS
