I have created a Canvas app and it runs perfectly on SF developer account 1.
In SF developer account 1 it appears on the Chatter tab as a button in the left menu (classic mode).
I create a package and upload it.
I then login to SF developer account 2 to install the Canvas app from the installation URL.
It says installation worked for SF developer account 2.
The canvas app appears in the App menu; however when I select it, nothing happens.
No error message, no iframe container and it does not appear as a button in the left menu of the Chatter tab so that users can launch it.
Can someone please provide a solution or things to try? Thanks!
