Eh, if it's going to be this hard to even meet her, I would not hold your breath for much coming from this.
She doesn't sound ready to meet people. I get that she wants to be cautious but she also needs to understand that most guys on dating apps aren't looking for digial pen pals.
You could try asking her for a phone call, but if she dodges this or instead wants to just keep chatting, I would wish her well but move on.
