Earlier quoted context omitted.
Not the OP, but on Bumble, I matched with someone who I knew - she showed me her app and no such match had appeared on her app. I think this sort of behavior is not uncommon.
Any more info on this or maybe some screen shots? I'm not on the market but given the complaints about the current state of dating apps I think lots of people would be curious to see this.
for instance, to those who might say "she just didn't want to acknowledge you had matched," I saw it with my own eyes and also we were already involved with each other at the time.
FWIW, my perception is that this is not the case on Tinder, but obviously can't be sure.
