So, this is solved from twitter end automatically but what's strange is it started working without any update or intervention from my end or any settings change.
Good to know.
Really strange. That scares me a lil to imagine that changes are happening without our knowledge.
How do you think this is possible for an app to start working on its own?
I also checked with a couple of people on twitter across the globe who faced same issue & for them also it was a sudden start.
