OTA updates not being installed on Poco F1

I have Pocophone that I moved to /e/. I have an issue that OTA updates are downloaded but not installed. If I am trying to install them, the phone undergoes the same process as on my daily driver (/e/ as well): preparing installation etc. the phone restarts but then the new update is not being installed. No error messages are appearing.
If I do it manually via TWRP it works.
Is this a bug or is there something obvious that I may have not respected causing this behaviour? Anybody with similar behaviours?

We had a similar issue on the MiA1 sometime back, There was a resolution which was proposed you can try the same.

Hm, no success.
The sideload part worked out, but subsequent OTA-update didn’t work. Any other idea?
