All forms suddenly stopped working across all sites

All forms across both of my sites suddenly stopped working when I added a new email to send submissions to. I’ve tried everything including reverting my settings and all forms keep telling me something is wrong. :frowning:

I am having the exact same problem today. All forms across all sites not working. Were you able to get it working in the end?
