The connection between MacPay and the iPhone does not depend on MacPay+ but on macOS. MacPay+ integrates Apple’s Continuity technology, which allows you to scan a bill with a QR code directly from your iPhone, without additional software.
This technology requires strict conditions to be met in order for communication between your Mac and iPhone to work. MacPay+ has no influence on how this connection works: if it works, the functions are active and MacPay+ receives the scanned QR code; if not, the functions are greyed out. The problem cannot be solved on our end as it does not depend on our programming.
You may also notice that the problem occurs without using MacPay in other Apple applications that use this technology, such as Apple Mail and TextEdit.
The conditions imposed by Apple for operation are as follows:
Your devices are close to each other and are configured as follows:
1.
Wi-Fi is enabled on both devices. If you have multiple Wi-Fi networks, for example separate networks for 2.4 GHz and 5 GHz, make sure that both devices are connected to the same network.
2.
Bluetooth is enabled on both devices.
3.
Your Mac and iOS device are connected to iCloud with the same Apple ID.
4.
Your iCloud account uses two-factor authentication.
5.
Your Mac is running macOS Mojave or later, and your iOS device is running iOS 12 or later.
If all of these conditions are met and scanning still doesn’t work, restart both devices.
If you still can’t enable scanning, here are some things we found in our research that you can try:

A relatively detailed article on possible causes.
b.
Another possibility is to delete a file containing the Bluetooth settings and then restart your Mac.
