Girlfriend not coming into my world, Minecraft?

I wanted to ask what we should do because I send her invitations all the time, but in the end I only see that

So it practically shows me that she is in the game and even if I go to sleep at night I have to wait until she comes, while she only sees the following picture all the time:

What should we do. You can't go into any of my worlds, but I can go into your world. We both have the pocket edition

Your connection is not good. Try again if it's better.

you can also just be friends with her in the game and then play, which gives her automatic access

This may well be due to your internet

Uhm how do you think i can be friends with her in the game if you mean this microdot account we're already friends
