Version 126.96.36.199 is now live in the Store. Unfortunately, no changelog is present and seeing as this is a minor number change (up from 188.8.131.52 just a few weeks ago), we are guessing that this may address a few bugs or performance issues.
Indeed, one complaint we have seen is in relation to the rotation within the app affecting rotation for other apps. It is not clear if this update addresses that, or exactly what is causing that random bug.
