When one of my patrons tries to log in (via the WP plugin on my site), she gets the captcha over and over, she says she submitted the images 10 times and it just kept giving her more images to confirm. Cookies are enabled in her browser and here’s the info: https://whatsmybrowser.org/b/28AXVV7
I experience this (not endless but ~10 captchas one after another), logging into patreon.com. It is really bad. Probably many potential patrons give up and don’t login.
