So am I. (Albeit not recently – but the experience never dies.)
This is the golden question. We can safely guess that Switch takes longer than other platforms (due to its client updates typically releasing later), which in theory can only be attributed to a longer queue length or more steps in the verification process. And for the larger version updates, it’s likewise a safe bet that the dev team accounts for this expected delay in their pipeline – either by submitting it sooner (than other platforms) or by requesting a scheduled release once verification is finished. (Switch HAS received some clientside updates concurrent with other platforms)
Only when it can be fixed from the server side, without requiring a client software update that the platform holder demands time to scrutinize before rolling it out. Like, say, putting a Mythic trait on an Epic Troop. That didn’t require any changes to code (clientside), only data (cloud/server based).
Alternatively, name any prior GoW clientside hotfix/update that was “pushed out in hours”. I can wait.
