This guide mentions that Meta Collections have a limit in the amount of collections they can containhttps://community.funnelback.com/knowledge-base/implementation/best-practices/best-practices-gather-and-index/best-practices-collection-types
Can someone tell me what this number is please as I think I may have hit this limit (64), as adding any more collections causes the Meta Collection to throw an error and breaks.
It's currently 64, and if any push collections that are included will reduce this (because they are basically like meta collections with their own components).
There is an open improvement ticket about increasing this limit.
