Large amount of app downloads on tuesday

There's what's called "auto migration", where in the store, a new device can be added with no action by you.  This is often a new APAC version of a device.  That means anyone that's using your app get's the "new" version" The chart will show a spike but your total downloads wont really change.

If you look in the developer dashboard, you'll see something like this for your app:

This one was auto-migrated, and the gear is an indicator (hover over it and it will tell you).

Since it's a new version, it also acts like if you'd done an update yourself. so things like "most popular" will change.  There's a setting for apps in the store to turn off auto migration.

The way it works is if your app supports a device that's basically the same, it gets auto-migrated.  So if it supports the ROW version of "A", and a new device is being added (say APAC "A"), it gets auto-migrated.  But if APAC "C" is being added and you don't support ROW "C", it won't.

Out of interest, does that mean there is a change to the SDK with new supported devices?

EG: If I had, for example, done a big rollout of new versions of apps immediately as the auto migration occurred, would I then need to update them and do it all again?

Using what I said above, if you had done your own update before the auto-migration, "APAC B" would be available.  But if you update after the auto-migration, you'll likely lose "APAC B", until an SDK is released that knows about "APAC B" and you updatew with that SDK.

But it might not be too bad, as not many people will have "APAC B" for a while.

The drive behind this is when people do start getting the new device, there will be a bunch of apps in the store for them already, without a new SDK or all the devs updating their apps.

Fair enough, I won't sweat it.
