App events should include OS tag. These complex queries seem to only be needed when data structure doesn't fit your use case
That's what I had to do but implies data duplication. The platform information (OS/architecture) is in the 1063 event where it should belong Anyway I was bringing it up regardless of this particular case
That's what I am saying - the general solution is data duplication, not complex queries. We duplicate events across relays already, duplicating fields across related events makes as much sense.
