For the future: It was ok to send the soft close, but she ignored it, therefore you should never push further but instead build more investment an try again later

Your elo will adapt. I would cut the staged photo with shades and blue shirt as well as the line "I'll ruin your life", upgrade to platin, don't show your distance to other users, set your locations to somewhere your type is more appreciated around 19 o'clock, you will gather an ass full of likes there, 3 days later set it back to where you are living, show them your distance, activate your free boost at 19 o'clock BOOM

To make sure it's not a software issue, reinstall the app.

I had the "no matches" issue, when I was setting up my profile week after week, someday I had to wait a bit longer for the newby boost

I wanna add to lines which work great for me. Feel free to give them a try.

In a situation where "Don't be shy" works, I mostly go with "there is no perfect answer 😉", assuming that she takes her time to impress me, but also encouraging her to be real

If she doesn't respond after the "Soft Close" I use the "If you are nervous, I understand" line. Usually they respond with "thanks for your understanding", I follow up with "What holds you back?", which is a great text to get to the core and bypassing the trap of leaving the buyer-frame
