Yes, I tried that, no luck on my side. I already completely removed Hubspot, then started a fresh install and connection, it shows all good in Hubspot dashboard, but nothing happens in the Office 365 web. Support told me to call a number so they can connect and see what is going on, but not planning to spend another 2 hours to find a fix. Hopefully they will get enough support tickets and realize that there are some issues that need to be addressed.
