Outlook Mac - Glitchy formatting behaviour

I have been using the HubSpot Sales add in with Outlook 365 for the web for several weeks now without issue. Decided to switch over to the Outlook desktop app beginning today in order to see if things work as expected with it too.

My computer is a 15" MacBook Pro (2017) running macOS Catalina Version 10.15.7, with Microsoft Outllok for Mac Version 16.46 (21021202)

Along a similar vein, my boss (the company owner) has not been using the HubSpot Sales add in due to the behaviors described by @AJV above. This is causing a bit of friction within the organization as his email corrospondance with key contacts is not being logged within the CRM, and whenever we’re Cc’d in any of these emails we go into the contact and manually log the email. Hoping to win him over to using the add in if it works now. There is one issue though, as he is on a newer MacBook Pro running macOS Big Sur, which is not the exact setup I have.
Just about all other employees use Windows-based computers and are not reporting odd behavior with the HubSpot Sales add in.

If @AJV @djaytch99 or @JessicaH has any recent updates, I would love to hear about them. Thanks!
Cheers,
Lee
