Firmware update for Zip

[Myhushpuppy]

Ever since I bought my Zip in Feb it has said there is a Firmware Update available. When I click to update I get the message that it may take up to 10 minutes but a couple minutes into it I get the " not working?" message. I've tried doing it on 2 different devices including PC and I get the same thing. I've restarted, I've relogged, I've changed battery. My dashboard says I'm on version 5.72. Is this the current version?

Thank you.

I've had my zip for several years & my firmware version is the same as yours .

Every time I open the app it says "firmware update available"...does yours say that too?

No I don't get that message.

When I first got the Zip in 2013 it did not have a message "update tracker software" but it has been there for about a year now. I am also on firmware version 5.72. I have tried all the same things as you and it will not update.
