Hi,
I installed and activated the ACF Pro plugin via the X Addons menu.
Now, WordPress shows me under Dashboard -> Updates that there is a new version for Advanced Custom Fields Pro available (v 5.5.3 – installed is 5.5.2).
However, when I select the plugin and click the update button, I receive an error message:
Updating Plugin Advanced Custom Fields PRO (1/1)
An error occurred while updating Advanced Custom Fields PRO: Update package not available.
Is this related to the activation without license key (as it is bundled in X Theme)?
