My Magic Trackpad 2 has input lag the first time you touch it after more than, say, a second. Apple support said it might be interference and to turn off any other nearby Bluetooth devices. Oof. Ok, thanks.

Perhaps the next product I buy from them in an Apple Store I’ll pay for by wafting my card around the contactless terminal a little before walking out the store saying “if it didn’t go through, try turning off any nearby devices!”
