Pix4Dcapture doesn't start after update

Hi

After updating ios for v 11.2.6 (iPad air2) and also update for the last version of Pix4Dcapture, the app at the start goes directly for background environment even before I can see the main menu.

It is open in background but I cannot call it to use it, stays always in background

Please help

Just reinstalled and it seems to work fine now.

Thanks
