Get off the dating app if you can to something else.
Hit her up for a meeting within 2 weeks. 1 week if you're getting on ok. Anything but a "yes" and a firm date, block and move on. She's just there for the validation.
She is going to decide within a few minutes of meeting you if she likes you.
If 1st date goes well, talk about 2nd date ON the first date. Don't leave it to later texts.
Preplan both dates in advance. At least know what you want to do. You're paying, so you get to decide what you do, something you like, but no food on the 1st date, it makes a good 2nd.
