Hi, i got an error when scan using iphone X.
After scan the QR code, in my phone just keep loading for a few minutes and nothing happen.

Second, success scan QR code on Android and then unlink the devices. After success unlink, i try to link again and got an error like this "Can't Link Devices".

Please help can you fix this ?

have you generated the codes while your whatsapp has less than 4 devices connected?

less than 4 device

If this occurs only when you connect a device after removing it from Whatsapp.
Then it could be something in your client store. I fixed this by deleting the db entirely but i suppose client.Store.Container.DeleteDevice(client.Store) may suffice.
