Oh trust me. Every dating app/site comes with its own issues. That's awesome you are giving it a go though! I actually met my SO through grindr about 5 and a half years ago and we've been happy since. :)
:O I swear you were in a long term relationship when I left mid 2015? I also met my OH on Grindr, just had to kiss a lot of good looking frogs to get there.
