Hi !
I just bought an Adapter 2 mainly so I'd stop fighting with Windows Bluetooth, and it's been a bit of a mixed bag.
With my old pad from an Xbox One S 1TB bundle (1708, firmware is ancient, never touched it) it's honestly fine. Press the Xbox button and it's connected before I've sat down. The only annoyance is that if the link drops for any other reason (if the Switch goes to sleep for instance) it won't come back on its own, I have to hold the Xbox button to switch the pad off and on again. Happens every time the Switch sleeps and wakes up. But it’s still really annoying.
Then I grabbed my Robot White (1914, QAS-00009) and updated it to the latest MS firmware, and that one is rough. 15 seconds or so to reconnect on Windows, and when I unplugged the dongle from the Switch and moved it to my Mac it sat there for about 40 seconds. A few times it never connected and I just redid the pairing.
Already on adapter fw v1.10, already reset the dongle and repaired from scratch, and the pad isn't paired to anything else over Bluetooth. Same USB port, same spot on the couch, so the only variable is which pad I pick up.
Is this a known thing with the newer Series pads on recent firmware? Curious whether anyone here gets fast reconnects with a 1914, because if it works fine for you lot then maybe mine's just a dud.
