Very happy to discover this again. I thought given the lack of updates for the IOS version that it had been abandoned.

On a 27" iMac at maximum zoom there is an out by one error, anything on the right hand edge can also be seen on the left hand edge.

(Edit) This is with horizontal and vertical wrapping enabled.

Also with wrapping there is a 2 cell horizontal and vertical sea section on the map.

The iOS mobile app is a different product,  Apple made it difficult to support and they finally booted it with the OS upgrade.

In EDCE , If your map is small enough to see the whole thing, this will happen.
