Multipage app with dash==2.5.0

I followed teh instruction using the very first example from here: Multi-Page Apps and URL Support | Dash for Python Documentation | Plotly
After converting my app to multipage, it suddently say this for every input id:
Attempting to connect a callback Input item to component:
“prediction_button”
but no components with that id exist in the layout.

hi @SaadKhan
if I recall correctly, Dash v2.6.1 has fixed a couple of multipage bugs that existed with 2.5.0. Can you upgrade the Dash version and see if you get the same error?
