@Jacob_PL_A as I mentioned in the post, it happens only to some users and occasionally... Which makes me believe that the configs are correct, otherwise, it wouldn't have worked ever... for anyone...

That is not the case. The app has access to both... And I doubt there is something off in configurations because otherwise, widgets wouldn't have worked at all. The issue happens randomly... Usually, after installing a new app version, the previously working widget shows placeholder data (like a skeleton)...
