Payment Stuck on Loading Until Reader is Reset (iOS, v2025.3.0)

[alunparanggi]

Hi, I’m experiencing an issue with the Square Mobile SDK Flutter package (version 2025.3.0) in my Flutter application (iOS only).

Here’s the scenario:

• After our staff serves a customer and completes a payment, they move on to the next customer.
• The Square Reader status shows “Ready”.
• However, when attempting the next payment (e.g., contactless), the payment screen only shows a loading spinner and never proceeds.
• This happens even though the gap between payments is only around 5–10 minutes.
• The payment works again only after disconnecting, resetting, and reconnecting the Square Reader.

Question:
What factors could cause this issue on iOS, and what can be done to prevent it from happening?

Additional Info:

• This issue occurs in multiple stores across different devices, ranging from iPads running iOS 15.6 to the latest iOS 18.5.
• I’m aware that there’s a newer version of the package available, but I haven’t updated because some of our stores are still using older iPad models that may not be compatible with the latest SDK.

Thank you in advance for your help.
