Hi Thunkers, In my app, I had set up a listener on my loading page which referred to any changes in the Firebase RTDB Users root node. [image] I then added The data change block to each screen where I needed the Event Listener. [image] This was working at one stage but I haven’t visited it in a…

Thank you for your reply @domhnallohanlon You suggestion regarding Variable names is noted with thanks. Here is a much simpler example that doesn’t involve Firebase: [image] Thunkable Screen two is a simple one second counter which works happily in the backgro…

Hi @domhnallohanlon , Should I expect any support with this? Any work around I come up with is extremely inefficient and messy. Listener Callbacks are essential to my application. Am I doing something silly or is this a bug? Thanks.

hi. can you try the block? i see the value of a in the screen1 when click to button. [Untitled]

Hi @eddie.rebehy , I changed the variabes to [cloud] and your App worked like a charm. [image] I tested it without initializing the variables but did not work. Once the variables initialize [A] acted as expected.

Yes you are right. I just changed that. Thanks for making me aware that the listener works for initialised cloud variables. Unfortunately this won’t work in my case because the variable names are unknown. They are created when the user is created. Thunkable doesn’t have a block to allow initializa…

Have you tried the [Data Changed] event of Firebase. [image] It returns the [key] name and the [value] of this key. Using successive if statements you can determine which [key] was changed and what action you want to take. Just a suggestion.

This is what I started with. It won’t work on multiple acreens for me.

@muneer @domhnallohanlon [image] Thunkable And just like that…without any communication from the Thunkable beavers… It starts working for all variable types. Muneer; please confirm that I’m not losing my mind! Time to test this again in my app. :crazy_face: …
