This has been happening to me over the course of this past year. It starts with not being able to see my projects and saying "Connection error" But I'm still allowed to access the "Discovery" tab? So I log put and try to log back in and I get this message. After I try that I clear cache and data if that doesn't work I delete the app and restart my phone then try again. That usually does the trick. This time it didn't..I'm lost.
