The cause is `gs_plugin_add_alternates` doesn't set the `snap::confinement` metadata item, so the channels other than the default aren't detected as classic.

In the top right dropdown, it asks for the source. For Andoid Studio it displays Ubuntu. I was suspicious of it being a deb and not a snap. So I clicked on it and it shown me 3 Snap channel options. I selected latest/stable. The source changed according to my selection. Then I tried installing it but it failed saying: Unable to install "Android Studio": snap "android-studio" requires classic confinement I was puzzled. So I went back to the search menu, I clicked again on Android Studio and the source was now again on Ubuntu (note that this is not an option available in the dropdown). I checked the details and indeed it's the snap package from channel latest/stable, just the source is somehow misleading. Now it installed the software without issues. What doesn't work: - Source dropdown (top-right) shows "Ubuntu" instead of the snap channel - Selecting a channel breaks the install functionality for classic snaps (it seems like it attempts to install them without --classic) Workaround: Do not select any channel, just use what is provided, and it works. If needing to use a different channel, use the command line (or perhaps check if this works in the Snap Store, if it has not the same issue).
