A bit of an update:
I submitted a Jira yesterday and got a response earlier today from Harley Linden, stating that the "engineers are aware of the issue and they are working as quickly as possible to resolve the trouble."
The ticket was also marked as resolved since support isn't able to help directly with the issue. But, it is being looked at/worked on, so that's a plus.
A bit of speculation: but on the occasional time i was able to access the first page of the favorites, there were new sorting methods, such as: "age: newest added to oldest" and "age: oldests added to newest" in addition to the standard "relevance, newest, oldest, etc." So perhaps the implementation of that update is creating a hiccup in the server(s)?
Will add updates as i notice them beyond that.
