Nokia 8 - Revert OTA for Beta Androind 9 isn't working

I signed up for Beta labs, so I'm running with Androind 9 Beta right now, I am aware that there is official 9 on Nokia 8 devices right now, so if I wanted to get it I should request for revert OTA to android 8 and then I would get it. So, I requested for revert OTA yesterday and didn't receive any till now. Any idea as how to proceed further? anyone?
