Thank you for commenting on this issue with your feedback. I’d like to give you a quick update on this feature improvement. We’re continuously investigating solutions to improve performance, but loading & viewing a very large amount of issues at once is complex.
The issue & project limits most likely won't be extended in the next few months. The Reason is that we chose to invest most of our effort in simplifying the UI with a brand new design, details can be found here.
We know that this is a major issue for some of you and longer term ( 12-18 months ) we will increase our efforts to extend these limits in a way that won’t lower performance.
In the meantime, I would advise customers to split their work streams into different plans. You could use the Programs feature to get an aggregated view of multiple plans, for basic reporting functionality.
