Not that I've noticed.
But the bingo option itself has changed, or is at least different from what's on this page.
Instead of 'Unbingos everyone in your village.'
It is now 'Lowers Entire Village's Bingo Timer by 1 Hour'.
Unless that changes when your village gets to a different tier. My village is T1 atm.
Nope, that's what it's now been changed to, and it does not, in fact, trigger cooldown. It's like a village-wide Juicy Apple, now.
Does it lower you time by one hour too or just everyone else in the village excluding yourself?
I answered my own question. Maybe it should be added that the bingo favor actually does lower your own time by an hour too.
lol yea as you can see from the posts above it used to be a good way to unbingo yourself at any time without cooldown at the cost of a favour (used to be moderately expensive), but now it doesn't really do that anymore… unless you have a 1hr softbingo and are desperate…. meh really desperate
