Yeah, I'm in the same situation.

I just opened square on my phone. There's still no message about any updates. I'll call them today, hopefully their phones are working. Or maybe someone here will reply with information.

I spoke to Square. The update mentioned in the email was supposedly for "Canadian sellers." Since I live in NJ I wondered why I had been sent the email but support had no answer for that. In any case, support checked my app and told me that I had been updated at 7:30AM yesterday. I connected much earlier than that and I know there was no message displayed when I connected so it must have been pushed later in the day when I wasn't watching. Support then told me that I had the latest firmware - 3.1.59.

I hope that helps.

I guess 3.1.59 is the same as the 301059 that mine shows!  Thanks!

Thanks, Joe!

My reader shows firmware 302075, which I would gather is the latest even though the thread shows 301059 to be the current/latest. Does the firmware depend upon how new the reader is? 

Hey @karlzsuccess! Because you're a US seller, you don't have to worry about updating your firmware at this time. The update was for Canadian sellers since we recently added the capability for them to accept chip and pin payments. Continue to ensure your Square app is updated, but the Contactless and Chip Reader itself will update periodically on it's own.

We will definitely post an announcement in the Seller Community if/when we do need our US sellers to update the firmware for our hardware.
