I use it at work all the time and frankly, it’s completely functional. I also prefer the Bing image search over Google images search these days… And I was a hardcore googler back in the day!

Same. It worked great for me with the profiles (personal microsoft account + uni microsoft account) until my uni disabled the bookmark syncing feature for all our accounts. For some odd reason.
Then I switched to Firefox and I’m not turning back.

I used and liked it for a few years, but now they started filling it with bloat ware again… switched to Firefox last month.
