Ok cool so you have a good connection with her. Her sudden Lol's seem out of place, as you mentioned. A guess here... she wanted weed. Perhaps you lost her with your interest in psychedelics, merely speculation though. The fact is, the convo dropped off, and the ball is in her court.
My advice: do not send her any more texts until she responds to you.
You mentioned the app you're using she does not get notifications? Help me understand this. How do you know her? how long have you known her, been talking, what sparked the conversation in the first place, etc. I'm wondering why you have her on "this app" instead of using snapchat or texting her.
My advice, continued, until I get more info from you,
If you have her on any other social media, for example snapchat, take snaps of stuff that you are doing (send to your story, not to her) and bonus points if you take snaps with your buddies showing that you have a fun social life and are a fun person who is busy doing fun things. Make her see this. Of course, do not talk about it...don;t say her did you see my story / my instagram / whatever... just post things and allow her to see it. Instagram works too.
When she does finally reply, act like there was never a break. Everything is still cool and congruent, and not talking to someone for a few days is normal. People get busy, things come up, its normal unless youre in an official relationship. In other words, shes not your girlfriend so its unrealistic to expect her to text you all the time / for her to always text you. Allow her to see that you are not needy. Do not make the mistake of being arrogant. Yes, you have stuff going on, but also you are interested in her so it would be weird to pretend like you don't want her attention at all if that makes sense. I'm happy to go into more detail on topics of interest for you.
