We’re seeing an issue with our POS UI Extensions when upgrading iOS devices from version 9.26.2 → 9.27.0

Has something significant changed in this release? Prior to upgrading the app, we had the (then) latest (9.26.2 ) version of the iOS app installed and are working with the latest stable version of the POS UI Extensions - 2025-01 .

After the upgrade we’re seeing the content in our modals completely squashed and taking up about 25% of the available horizontal space.

We haven’t updated anything in the code on our side, just the update to devices. And to reiterate we were on the latest versions of the app and extensions before the update.

The release notes for the new version are ‘- General improvements and bug fixes’, which doesn’t give any clues.
