Works fine with no issues in Firefox.
I am able to get it to load slow in Edge. Chrome is choking. Makes sense since Edge uses the Chromium Engine under the hood.
Still looking into why...
Just an update here. I'm still not able to recreate the issue on my devices, nor is there any indications of an issue on the various test services.
There is an issue being noticed in 'real world data' on Google Chrome though where the profiles are lowing slower. We are still working on it.
As far as I know, there hasn't been a change to how notification follows work with regards to Status updates.
The only change to the system I know of is adding push notifications. We updated the default settings at that time to account for the new option and fix some email notification settings.
