A: Hi Mark :)
You mean by product upgrades purchasing more credits ontop of the lifetime plan? If that's what you mean then yeah, if we introduce such updates, they'll be available for sumolings.
At this point, whatever we build for our subscribers we give to sumolings too, for example, we made a massive update to the app to go from credits 1-click generation to a smart agentic chat, and we gave that sumolings too, so yeah that's not an issue
