What’s my next move?

Ok here’s a pretty low stakes one and I just want to see what my next move should be. I (26M) matched with this girl (21F) on Saturday night on Hinge and started talking and getting flirty. Long story short she suggests we hang out and says “name a time and place”. I tell her I’m free Monday night and she doesn’t reply until Monday at noon saying she didn’t check the app until now but she’s down if I still am. I say yes but later that day she has something come up and says she “likes my vibe” and is definitely interested in hanging out some time this week and asked for my schedule. I gave it to her along with my phone number for easier communication but haven’t gotten a reply as of Wednesday afternoon. How much longer would you suggest I wait before a double text and what would you say in it? I know this isn’t a very compelling situation but I’m just curious to hear some opinions.
