Users are facing checkout error - "Something went wrong. Please contact the developer of this application and provide them with this error code: checkout_already_presented"

So, even if we are getting recent SDK, our users are getting the attached error.
Our support people helped our users by uninstalling the Point of Sale app, disconnected the readers and setup everything again.

Can you please let us know why our users are seeing the below error?
The problem is… we are unable to replicate the error when we try on our side.

One of the user getting error “reader_settings_checkout_presented” has these versions:
iOS: 15.0.2
Square: 5.75
CARD READER: Contactless Chip Reader
Model: spc101
