Official clarifications published for this card.
This card's [When Digivolving] effect placed a [BT10-016 Jesmon (X Antibody)] as a digivolution card, then that card's [When Digivolving] effect played a [BT6-082 Sistermon Blanc], then I activated <Blitz> in this card's [When Digivolving] effect to attack. When does [BT6-082 Sistermon Blanc]'s [On Play] effect activate?
Since both the [BT6-082 Sistermon Blanc] having been played and this Digimon attacking with <Blitz> happened during this Digimon's [When Digivolving] effect, the Digimon being played and the attack are treated as having happened at the same time for the purpose of triggering effects. The turn player can choose the order in which to activate the [On Play] effect and any potential [When Attacking] and such effects.

This card's [When Digivolving] effect placed a [BT10-016 Jesmon (X Antibody)] as a digivolution card, then that card's [When Digivolving] effect played a [BT6-082 Sistermon Blanc], then I activated <Blitz> in this card's [When Digivolving] effect to attack, and when the [When Attacking] effect deleted one of my opponent's Digimon, my [BT6-082 Sistermon Blanc] was deleted by the [On Deletion] effect of the opponent's Digimon. [BT6-082 Sistermon Blanc]'s [On Play] effect hasn't activated yet, so does it activate?
No, it doesn't activate. The [On Play] effect from [BT6-082 Sistermon Blanc] was triggered, but it cannot activate because the [Sistermon Blanc] is deleted before it is able to activate.
