A card that was given "can't activate [When Digivolving] effects" digivolved into a card that has a [When Digivolving] [When Attacking] [Once Per Turn] effect.

No, it doesn't count. The effect can't activate upon the [When Digivolving] timing, therefore it doesn't count as an instance of that effect's [X Per Turn].
