I have a Canvas App embedded on a custom entity in Dynamics 365. I have made the app custom size, in two lower environments, the app renders correctly according to my custom size. But the issue is, when moving up to a upper environment, suddenly on the form there are extract white spaces appeared with the app section below where I put all my controls. I tried different accounts in that environment, changing the size setting in that environment, and re-adding the embedded Canvas App field but issue still persist.
I have found a link on the community where others also encounter the same issue, but their solution is regarding a setting on the Security role to show on organizational level. But I am using a System Admin account, and the white space is still there for the System Admin account.
