The sync source sounds like a likely reason, it fits with the ‘actual’ output since i only ever receive the second observable’s items. And you’re correct Edward about each observable needing at least one item, however my results are emitting 2, and 4 items respectively, not 5 - at least in this synchronous environment. Anyway, thanks for the sounding board - you guys are way more fun than my rubber duck collection 😉
