My one experience was a girl said she liked dogs on her profile and had a picture of her with a dog.... when we went on a date I asked her about said dog and she was like "I don't like dogs, I'm a cat person"
In that moment I was like "I think she's crazy" not because she liked cats, but she had clearly said she liked dogs and had a photo with one prior to that (which she claimed when we started DM'ing that she owned)
The next 5 mins she would only give me 1 word replies when I tried to get a conversation going, then I went to the bathroom and when I came back she was gone
I mean it's possible the app has changed in the last 6-7 years, but they probably only added more ads or pay features
