Problem with downloading Africa West Map in iPad mini 4

  • Hello,
    I downloaded the new Quo Vadis mobile on my iPad mini 4 and on my iPhone SE.
    Well, I tried to download the Corsica map on iPhone : perfect
    I tried 5 times to download the west Africa Map on my iPad mini 4 with 12,4 gb available, but the download seems successful to 100% but when appear "importing Africa-West.qmr" the round circle continue to work for many hours without success.
    I think that there is a bug to fix.
    Thanks
    Andrea :(
