In the early stages if a woman is keen on meeting up but is unable/unwilling to commit to a set time, am I supposed to leave the ball in her court or should I reinitiate at a later time?

For reference, I'm a 24 year old male.

Now I believe in the ideas of fuck yes/no, if a girl is interested in you she will make the time to see you etc.

I get quite a bit of matches on Tinder and I'm usually able to get women to express interest in meeting up and get their number/snap/insta/whatever.

Quite often though, when it comes to the logistics of organising a time for meeting up, they'll be either unable to indicate when they're free in the near future or if we do end up setting a date, asking to reschedule.

Normally, when this happens I text them something to the effect of "no problem, I'll leave the ball in your court to reschedule and/or let me know when you're free etc" and then don't message them again, focus on talking to other girls etc.

However, I've never really had a woman reinitiate contact after this so we never really speak again. I'm curious if this is the wrong approach to take and if I'm leaving potential girls on the table by not reinitiating contact at a later time- especially given it's the early stages and they're tinder girls (who I would imagine would get quite a lot of attention).
