This is not about pairing. I have paired these headphones fine.
I have had 2 other cheap pair of headphones that auto connected perfectly. I decided to upgrade to the Sony WH-XB900N. Pairing went fine. I have them set to auto connect on my Roku Roku Streambar Pro . The problem is they never auto connect. Each time I want to use them I have to go into settings and manually connect them
This same issue was raised back in March 2023. It was marked as "solved" back in 2023 stating we had to wait for the engineers to fix it. That was a novel way to clear the issue from the support queue when it was not solved at all. We are nearing 2 years now. Any chance it will ever get resolved?
