Update channel selection by user does may not match what happens in logic afterwards
As I've experienced previously (and as seen again yesterday in https://t.me/utonvolla/12988) selecting the update channels may not match what is downloaded and switched to next which is very noticeable based on the version numbers alone (very many for devel, fewer for stable etc) and can be double-checked from https://system-image.ubports.com/ on a per-device basis.
As an example a user on Volla Phone 22 with both 16.04 and 20.04 available had this strange upgrade path:
16.04 stable -> selected 20.04 stable -> ended up on 16.04 devel
16.04 devel -> selected 20.04 stable -> ended up on 20.04 devel
20.04 devel -> selected 20.04 stable -> ended up on 16.04 stable
So it appears something is wrong with the information presented and the indexes which end up getting selected for the channel on the backend of the channel switcher page even on 20.04 as downgrades to 16.04 are not possible or shown and should never happen.
This possibly affects all devices with both 16.04 and 20.04 system-image channels available.
