One of the annoyances I ran into trying to set things up on the new phone: Canon Camera Connect insists on using Chrome for its login flow. Not Android webview, not your default web browser, but Chrome. I actually had to install Chrome on a deGoogled Android to start using the app.
(I'm still annoyed that the app has started requiring a login in the first place, since I don't use any cloud-connected services through it. Just the local ones that let me save a location trace and add it to the camera's photos, or transfer photos from the camera to the phone.)
