Explanation

The mobile sync feature has been removed. It has been disabled for years. When we enable sync again, it will be using a different implementation. This has already been removed on the mobile side.

Pre-merge reviewer checklist

• Manual testing (e.g. pull and build branch, run in browser, test code being changed)
• PR is linked to the appropriate GitHub issue
