The video of John Cena returning at Money In The Bank has 3.6 million plays, and so far, there has never been one so played on WWE's Instagram.
The YouTube video of the event has a "moderate" number of 3.3 million views, even less than the IG video. Perhaps, the failure was that they took longer to upload it and that it arrived when it had already gone viral.
