Yup I’m getting this too. It just started.
I’ve been developing my first twitter app and running into limit issues & losing write access. I’m pretty sure I’ve gotten it under control in the latest version (7-8 posts and 1 or less searches per 15 min… unless each result counts as a search or something. I still lost write access with that setup, But I think I found the reason to be too many mentions so i just fixed that) but when I went to delete my last attempt and start a new app for my updated version with less mentions I got this. Is this a bug or did I get myself blacklisted with my testing/learning limits? How can I tell?
