What does "can't [...] activate <When Digivolving> effects" mean, exactly?
This effect prevents <When Digivolving> effects on cards from activating. Triggered <When Digivolving> effects can no longer activate when a card digivolves or when effects such as "activate that card's <When Digivolving>" effect" activate.

I used a card affected by "can't [...] activate <When Digivolving> effects" to attack. Can I activate that card's <When Digivolving> <When Attacking> effect at such times?
Yes, you can. The effect can activate if it's triggered upon the <When Attacking> timing.

If a card is affected by "can't [...] activate <When Digivolving> effects," can it activate its own <When Digivolving> effect using an effect such as "activate 1 of that card's <When Digivolving> effects"?
No, it can't be activated.

Can I use "activate 1 of that card's <When Digivolving> effects as an effect of this card" on a card that isn't affected by "can't [...] activate <When Digivolving> effects" to activate the <When Digivolving> effect on another card that's affected by "can't [...] activate <When Digivolving> effects"?
Yes, you can.

A card digivolved into a card that has a <When Digivolving> <When Attacking> <Once> effect while "can't [...] activate <When Digivolving> effects" was activated. Does that count as an instance of that effect's [X Per Turn] even if that effect can't be activated upon the timing when that card digivolved?
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].
