I used these blocks

#23

Does it work now that you changed them ?

My app is crashing due to some other reason. I am working to solve that first. (I guess its related to using two firebase realtime database url in the same app. I’m not sure if its possible, but my app worked initially but now unable to fetch data from the second project.)

Add two list into a third list, remove duplicates.

Then use this block to remove items from the longer list of the two

Ta-da!
