To make it even more complicated, there is no limit for renewals, but renewals also count against those 20 subdomains per week, so if you happen to have a few hundred internal subdomains, you will still run into these limits 90 days down the line, when the certs renew (I just had this issue and was able to resolve via their rate adjustment form and community forum; very responsive and helpful for a free/donation-based service).

These limits can basically rule them out for wildcards.  You can work around the limit, but it’s kind of a pain I suspect.

Here’s their docs on this:

Also, for a script to handle this, I like dehydrated:
