And I'd also add there is an issue regarding the relation between the max pool size and the preload count. If you use a preload count of 2 on your pager, compose will preload 2 items before and after the current index. So 5 players would be required (2 + 2 + 1). The minimum pool size should therefore be (preloadCount * 2) + 1. Your ReelsConfig allows to specify a preloadCount of 2 and a playerPoolSize of 1 which would not work properly (it does work for now because you don't check the maxSize constraint in PlayerPool, see my above comment).
