It’s also very strange that it only started happening after updating to WP 5.9.2. If I preview the form on iATS, it looks fine. When it loads on my page, it’s wonky.
I followed Cloudfare’s workaround for it and it didn’t make much of a difference as far as I can see. The buttons are slightly less stretched out, but still not round like they used to be.
Now I’m trying to do a custom stylesheet for it to see if I can workaround that way, but this shouldn’t even have to be a solution.
