Official Ruling
No, it doesn't unsuspend. The target Digimon is unaffected by this card's effect during the turn it activated, but the "this Digimon isn't affected by the effects of your opponent’s Digimon until the end of your opponent's turn" effect is lost when the turn switches, and then this card's effect prevents it from unsuspending.
