As best as I can tell from extensive testing, the "Filter" feature simply does not work properly, and it is not possible to accomplish what I've described.
Have you managed to solve this? I'm experiencing a similar issue, I cannot get the filters to work in the collector.
Wow, are you serious?
We just starting out, not sure if I should rather try out another platform.
Thanks, I'm going to look at https://github.com/heroiclabs/nakama
