I am a Pro user, and have been refreshing (replacing/adding) a large batch of plots today (1500 plots replaced, 1500 added today, then all 3000 replaced), and in the middle of the final refresh my Python API started getting “unknown error” messages. When I checked the website, I was given a message “Your account requires an upgrade! You’ve reached the daily usage limits of the free tier. Try again tomorrow, or upgrade to a paid account.”
I already have a paid account and have for months. I did email support, but thought I’d put it up here too.
