App not starting offline

LKWD — Sat, 20 Sep 2025 10:31:46 GMT

Till now, the app worked on my iPhone even though there wasn’t any data at the time, (connected it at night) and now, it says error and gives 2 options: “try again” or “log out”.

Anyone else have this issue?

Anyway to fix this??

Hi @LKWD- Thanks for reaching out to us here on the Square Seller Community👋

Is there a specific action you're attempting to perform when you see this message? Square requires an active Internet connection to process payments. This can be either a Wi-Fi connection or a data service (such as 4G, 5G or EDGE).

I'll keep an eye out for your reply!

I’m trying to use the iPhone as a barcode scanner to take inventory, and check the prices, and as of 2 weeks ago, I didn’t need to have a data connection to start the app.

Now, when I open the app, when on airplane mode/no data, it says:

Connection error

Unable to connect to the Internet. Please check your network connection and try again.

Try again

when I press Try again it says:

Connection error

Unable to connect to the Internet. Please check your network connection and try again.

Error code: FDBZ

Try again

Sign out

I haven’t updated the app, and it used to work without any data.
