BluOS App on iPhone cannot find/connect Powernode2

Hi,

I have now for one month been trying to connect the BluOS App on my iPhone (vers 13) to my Blusound Powernode2 after I got a new network - but so far without success. It worked beforehand with my former network (!). 

I have only been able to establish connection for 2-5 days after which the connection is lost again. My iPhone cannot not find the Powernode2 WiFi hotspot. I can type the Powernode2 network name but it doesn't help because there is no password to type in so the the iPhone cannot find the network and then you are blocked (!). 

I have reset, rebooted, unplugged the Player, forced hotspot, unplugged the router, done network reset, reconnecting to the network (wireless or using ethernet cable etc.), disconnected cellular/mobile data etc. etc. - all according the guidance in here as well as direct support/advice from the Support Crew. As per recommendation of the Support Crew, I have also talked to my fibernet supplier and have changed the WiFi channels of my router to 3 for the 2.4GHz WiFi, and 48 for the 5GHz WiFi in two different networks. This has actually made the situation worse because now, there is now connection at all and I cannot do the 'Diagnostics' and the App just spins forever.

This is so frustrating and ridiculous! I have spent so many hours on this and still it does not work. I can see that a lot of people have/have had the same problem but there does not seem to be a good solution. How can that be? Why hasn't this been solved? I admit that I am not an expert but shouldn't be required either.

Is there someone in here that can help before I end up throwing the player out and get something else that works better?

Thank you for support and advice!
