I would try using the following dependencies. stream_chat_flutter: '7.2.0-hotfix.1' connectivity_plus: '5.0.2'

[ChefQ]

I'll try it next week thanks. Question: Is this new hotfix a response to my issue? Or did it always exist, and I was simply unaware of it?

[ChefQ]

Works like a charm!!!

@IvanTrejoDev

So without connectivity_plus: '5.0.2' it won't work!

Thanks a lot!!!

[ChefQ]

Now closing the issue!

the hotfix has been around for a few weeks. It seems others had similar issues. Glad to help!
