*Recently, while checking the db, I found out a handful of known primes that were classified there as U (Unknown status), and assigning them to a worker for a PRP test automatically proved them prime by N+1 test.

Assigning numbers for a PRP test used to be available for U integers with less than 150k digits. However, it looks like yesterday the threshold was lowered to 100k digits.
I have spotted another similar prime in the U list today, but it has >100k digits, so I am unable to assign it to a PRP test.

Is anyone on this list submitting Primo certificates? I'm running a script to prove 300+ digit PRPs and had a load of near collisions between 480 and 495 digits. But I can't tell if whoever submitted them had any of their work wasted because I'd just submitted a certificate.

I've downloaded one, it was submitted by "Anonymous", made with Primo 4.3.3 - LX64 and the input file was /home/user/Downloads/primo/4/primo_1100000004583465610.in (does anyone recognise this?)

My script works on the smallest PRPs over 299 digits. So if you keep above the first 1000 PRPs you should be safe.
