We are working on running a Page context using a 9 Level Hierarchy and the idea is to expand/collapse click through the levels while the dependent Grids on 10th Level get updated [ Hierarchy Filter Context Synced]
Unfortunately - the card navigation response is a little sluggish and takes 5-6 mins to get the context updated on the supporting grids.
Additionaly - after 2 or 3 click throughs - the page does crash as well. We are already planning to get a replicated dummy model ready and share the same with Anaplan Support but wanted to get this out if anyone else has already encountered this and are there any specific do's/don'ts we need to keep in mind?
