Oh, that makes sense, thanks.
I just tested it a bit more on Nox while logged on to my Google Play account and it turned out it sort of works, but not exactly how I'd like it to. I tried it in pvp (arena) and while I still had normal cooldowns, my opponent did not. It looks like the mod does the opposite, makes it harder for me and easier for AI.
I don't know why my cooldowns don't work (they were fine on my mobile while on a guest account), but I think your mod might be working for both sides, it's just in your video you fought a low level team with no special abilities, so it wasn't noticeable. I'm thinking this, because it's the same for the IOS mod, it works for both sides and needs to be turned on and off between turns.
