My app is not functioning well anymore

Hi

I stopped developing my app for some time due to being busy

my app is published and was working fine, but when i came to check the app on thunkable, it does not work, i tried to download the .apk and i have the same issue

while they are the same blocks, no change was done to the blocks

My app contains Variables, Lists and Realtime Firebase

List handling has changed a LOT over the last few months. That is where I would start.

can you just share the blocks so we can check and see what is the problem

My app contains thousands of blocks so it will be very difficult to take screenshots @luv.ak.techt
