  1. I can not play the video and don't know what is the error.
  2. I see you only have one tag AllPosts, when dataChanged, no need to request getValue again.
  3. Any error in aicompanion?

First, thank you for trying to help me.
To be honest with you, this is my friend device because I don't have an android phone, but I have tested the app in 3 different devices and it showed the same error.
Here is the video:MIT AI
I can't use the ai companion because, you know, I don't have any android device.
Well, your second point is good, but what do I have to change? Because honestly I learned how to build a social media app on youtube.
Thank you for your advice, hopefully you'll be able to previewthe video right now.

Sorry I still can not see the video.

You can install some Android emulator on your pc/iOS, and in the emulator install aicompanion.

Well, I tried, but my PC BIOS is legacy, which means that I can't turn virtualization on, so I can't use the emulator.

Ok I'll try to upload the video on YouTube, then I'll send the link for you

Just make a capture of the error from the video will be ok.

You are using firebase. You are probably using your own firebase database. Where is your firebase server located? The built-in component only works with US servers. If you created a firebase service with a server in Europe, this will not work.
