So I just fresh installed Edge insider Canary to get its new logo and it's Version 80.0.323.0 (Official build) canary (64-bit).
during uninstall, I chose to remove all user data.
after reinstall, Edge insider Imported my reading list from Edge classic and that was expected,
but one thing that was strange was that it actually Imported 1 of my extensions too!
another thing, on my previous Edge insider Canary, I had downloaded and installed ublock origins extension from Google chrome store but now that I check on my new Edge insider installation, it's downloaded from Microsoft extension store.
these were nice experiences. I personally liked that Edge automatically checks my extensions and downloads them from Microsoft extension store if there is a version of it available there.
