Causes and fixes

If the issue returns after a fix, note your YouTube base version, ReVanced Manager build, and whether GmsCore is installed. Mismatched versions are the most common cause of repeat failures.

Before factory-resetting or wiping app data, export subscriptions where the client supports it and confirm you downloaded patches from the official ReVanced GitHub organization.
