As a guy who used to be on bumble (met my partner there) I will say that any conversation that started with ‘hey how’s it going’ just went nowhere 100% of the time. It’s so easy to ask literally anything else. We don’t know each other, what’s the point in asking how it’s going if all you’ll ever get as a reply is either “good, and you?” which doesn’t break any ice and introduces a lull on the conversation 4 messages into the chat or if it’s an honest “pretty shit, actually” the tone of the conversation becomes immediately weird because you don’t know each other enough to pry into that.
Things you could ask:
cuddled any cats lately?
what made you smile today/this week?
what song have you played on repeat lately?
play any games lately? (depending on if they list games as their interest, most matches I got listed board games)
This way you’ll immediately either find common ground or find differences between your everyday experiences that you can talk about.
