How often has a provider bailed last minute ?

I’ll start by saying I’ve been out of the game awhile.
But in trying to get back into it , I’ve had 3 different women in a row cancel last minute on me.

Is this really bad luck or is this more common these days ?

Not trying to name and shame or anything but I was looking to get back into the swing of things and I have taken a break after each one just because it’s a bit discouraging

All 3 were well reviewed and have strong reputations as well and had gone through verification process already.

I get that things come up and they probably see last minute flakes more than I can imagine; also I’m a first timer to them and I suppose if someone they know and like comes in and wants my time slot they bump me - that isn’t terribly unfair.

I guess I’m just hoping to see how common this is , sorry it was a bit long winded.
