Do I have to activate this card's [When Evolving] effect?
Will this card's [Your Turn] effect result in my Level 4 Digimon with <Jamming> losing <Jamming> when Digivolving to Level 5 or above?
Show ruling
Official Ruling
Yes, because the effect is only active during [Your Turn], the moment the Digimon becomes Level 5 or above, the effect no longer applies to the Digimon, and it will lose <Jamming>.
