I've paid for Pro Version, not reflecting

Hi, I've been using the Pro Version for some months now, however today the app shows I'm not on the Pro Version.

Diarium version: 2.9.84
OS + version: Android 11
Device model: Redmi 10

Have you read the Pro version FAQs and tried what is suggested there? What exactly happens when doing so?

It's alright now. Yay! Thank you so much for the follow-up 🙏
