Comment 10 for bug 1873996

That first link (in comment #7) contains incorrect information. Official documentation is at https://snapcraft.io/docs. For the chromium snap, the edge channel contains the dev builds of chromium (so equivalent to ppa:chromium-team/dev).

There are a few known issues with the snap package (https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bugs?field.tag=snap), but in general it works well for most users. Bug reports are welcome if you undertake some serious testing (don't forget to state that you're using the snap).
