No Mega Evolution Switch

[Owen Phillips]

I had my Mega Delta Charizard (I also tested with Mega Delta Scizor) and if I mega evo’d, the mega got KO’d, and I revive it using a revive/max revive, it is no longer mega evo’d and I can’t mega again. I lost like 5 battles because of this, plz help!

the not mega evolving is part of even canon pokemon, but the instant fainting might need more specifically explained.
