2D Bluetooth barcode/QR code Scanner not scanning product code in a proper sequential order.

Urgent Help Required please:

2D Bluetooth barcode/QR code Scanner not scanning product code in a proper sequential order.

Barcode/ QR codes when scanned does not come in proper order in iPads. Tested in notes and browser in iPads.

Note: 1. Scanner works fine with other Mac products and Windows devices. 2. Issues occurred after Ios update: Ios version: previous version <15, updated version >16. 3. Scanner does not need any firmware updates and does not have any support for it. 4. Tried everything like reset all setting/ factory reset/ erase all data/ force restart/ diagnose/ contacted apple support. 5. **Apple Case ID: 101946377186 **

Can anyone please suggest me something on it? As it seems to be the Ios update and version the possible cause that not compatible with the scanner.

I have also requested if we can roll back to the previous version: Apple support said they can't.
