I am a beginner at MIT APP Inventor and I stuck on a problem using Firebase as Database.
I am creating an app for window's glass vendors, at the first screen they creat an account using firebase authentication.After this, they can register their clients information in a listpicker, so they can check their clients name, phone number, address, email. The thing is we are working with two kinds of variables, the primary one is the vendor, and each vendor may have your own client list to check those information. I created two different accounts, vendor A and vendor B. In vendor's A I registered two different clients, after that I signed out and logged in with vendor B account. When I opened the clients list with vendor B, I could see those two clients information from vendor A. In this case, could this be a Firebase permission problem or something that could be fixed in my blocks?
Sorry about my english! Feeling a little bit rusty, but I hope you guys understand my question.
