Well the videos that play for the x2 bonus reward are supplied by the offer providers so, indeed, there may not be any available videos queued up for your accounts.
I have days where I get almost no videos so just in case I always start off with training the squad. Other times I might get a few videos in the morning and then more later in the day (But usually after 20:00).

Btw I've been observing a lack of videos for my account as well half-way through May. But on the other hand I've stopped browsing the google play store as often as before. Haven't done any new online purchases and other such too as of late. I might be losing a spot under their radar I suppose. All kinds of online activities can make those systems throw advertisements your way.
