Please test this in companion:
replacement.aia (2.1 KB)
I tried it.
(this is like pulling teeth...)
and how did that work for you ?
Yes, I tried to put an image picker in your aia file but it didn't work.
Why?
Did you just test it "as it is" in companion ? You can see from my screenshot that the replacements are working (here). I am trying to figure out where you problem with this lies...
Are you testing with the companion app or with a compiled app ?
