My app is up to date. I can login online. But on my iPhone it won't let me login. So I can't sync or view my stats etc. It says "Oops, something went wrong. Please try again. This operation couldn't be completed. No such file or directory".
I worked it out. Rebooted my phone. And although it previously looked like my app was up-to-date, it wasn't. So updated software and now all back to normal.
