[BUG] Bypass 1 Mega Restriction not functioning

[taserbolt]

I've tested the Bypass 1 Mega Restriction cheat, and found that it lacks functionality in both Gen 6 and Gen 7. In Gen 6, the Mega button remains grayed out in Double and Triple battles even after waiting 1 turn, and in Gen 7, the button just isn't there in Double Battles (this is after triggering Mega Evolution on 1 pokemon).

Do you have a video to demonstrate this? Also does single battles work? Don't think they've been tested on anything else other than regular single battles.
