2 official rulings from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

I use this card’s effect to prevent one of my opponent’s Digimon with no digivolution cards from attacking or blocking. If that Digimon later gains a digivolution card, can it attack and block?
No. This card’s effect is already activated, so the affected Digimon can’t attack or block until the effect ends.

I use this card’s effect to trash 2 digivolution cards from the bottom of 1 of my opponent’s Digimon. For the part of this card’s effect that reads “1 of your opponent's Digimon with no digivolution cards can't attack or block until the end of your opponent's next turn,” can I choose a different Digimon with no digivolution cards other than the one I trashed digivolution cards from using the first part of this card’s effect?
Yes, you can.
