Android play protect certification

[FrankSmith21]

Since joining the previous beta for UI 3.0 I have not been able to certify my device, I'm using a Note 10 Plus and can no longer pay contactless, update apps like Netflix or Disney+ or pay with Google Pay at an online checkout. I have followed steps using smart switch however it doesn't give me the option to roll it back to a previous version and I didn't make a backup before the beta (I know, rookie move! I definitely know better now). Is there anything I can do? Factory reset perhaps? 

Thanks in advance
