I bought some cheap gradients yesterday, and activated them right away.

they're still not on, so i have a few questions:

1. do you have to activate them in the game too somehow?
2. do they only show up online?
3. does it have a several minute lag for removing too
4. do they show up in old replays too?

if you can't answer all of the, please answer the ones you can. any help is good.

thank you in advance
