Is your firebase project using the US server or the EU one ?

If EU, then delete and create a new one with the US central server

You cannot append a value to a string.

Create a list in your tag, then you can append values to that list

You are using different projects (url)

Mais quand mm , l'application ne doit pas se fermer automatiquement à cause de faux URL ou abscence d'internet

How are you running your tests?

• on a phone, or

Could you provide a test aia in order to check it ?

This is a very old version of AI2 offline and wasn't update since 2018 I believe. If you want to use offline try AI2Offline download | SourceForge.net

I modified your aia in order to show you how appends works. I compiled it as apk, install it in my phone no errors. Works fine for me

Apk to test
