Update on my situation. I had emailed them 3 or 4 times and they got all the serial number details. Now weirdly it has started working perfectly with my phone. Not sure if it was coincidence or they did something on their end, but either I'm glad it's working as it's a great feature
I have the same problem here. I have the xiaomi pad 6s Pro and I have the xiaomi 14 ultra and interconnectivity doesn't work with them which was one of the reasons why I got them both.very frustrating. They are both global versions so don't really know what to do from here. Any ideas?
