Universal SSL Error!

I registered the site for Universal SSL, it was written in DOCS that it would be activated in 15 minutes, but it still did not activate even though it was 12 hours.
I said I’d disable it and turn it on again, but now it doesn’t show at all, what should I do? I cannot activate it again. please help

You can try changing CA using the API endpoint mentioned here - people are reporting that it fixes Universal SSL certificate issues.
