Snap-store does not apply channel change

I noticed the problem with the chromium snap: clicking on the stable channel, in the GUI the change was made to stable(1), I open the chromium browser and I’m still on the edge version, I look at the cli and actually I’m still on the edge version(2), I solved by cli: sudo snap refresh --stable chromium(3).
The problem is the same on ubuntu-software from the deb repositories.
