For updating our client websites we use MainWP (https://mainwp.com). Updates for the Meta Box extensions are not visible as plugin updates inside MainWP. Is it possible to make the updates for Meta Box extensions visible as 'real' plugin updates?
Hmm, can you try the "Check again" button in the Dashboard > Updates? That forces WordPress to check for updates immediately. I couldn't find anything related to the settings page because it only saves the API key, it doesn't check for update when saving. Is there a chance that you entered incorrect API key previously?
I manage about 75 wordpress sites with MainWP. 50 of them use the Meta Box plugin and extensions.
When i check for plugin updates (with MainWP) i don't get the updates of the extensions. When i go the the WordPress admin from one of that sites i see the extension updates. After that i am checking for updates again with MainWP, then the updates are displayed.
It seems that MainWP can not trigger the extension updates. When I log into the WordPress admin I see the updates.
I'd like to help with a solution to the problem. If you need information or a screenrecording please let me know. I have to visit all WordPress admin panels one by one to update the extensions.
