Read the thread I linked to you. Everything is categorized there into 4 categories which define if and how it is exploitable.

Ads for NS/TK (and extra tanks) work the same way normal NS/TK and extra tanks would (stored device side, cloud syncable). You can basically sync them the same way you would do with credits for pro upgrades. Just be sure you got progress saved first on the device you get your boosters from. it takes much time to do though for a relatively Small gain though, just farming one race is easier to get the credits for NS/TK. I also simply have over 200 of both saved, so...

ads for free stuff: start them simulatiously, wait for all to be finished, then press x in the ad on that device you wish to get you stuff (it doesn’t matter for tokens or boxes, it does for credits, ETs, TKs, NS etc., info/explanation is in the same list I described above)

free upgrades work the same as max upgrades in general, therefore they are sadly not exploitable (damn that would be OP, we never would have to pay a single credit for upgrades anymore ^^)

base rule is: whenever there is an interaction between something stored device side and server side there is a possible exploit (as also described in the other post, which I really advise you to read very carefully and concentrated again, since it’s kinda confusing I know ^^)
