As of last Friday, I'm no longer receiving email notifications about the Bitbucket repositories that are being watched in my account, even though I can see that several updates have been made by different members of my team. This means I can no longer see any code updates, comments, or merges from my email.
I still seem to be getting normal updates from JIRA though.
For reference, the email linked to my account is tyler.earls@ensighten.com, which is a Microsoft Outlook account.
