Question about GoPro Hero 8 Black

I also have the connection problem between iPhone and GoPro. I have already tried a few things there too. I disconnected all connections and reconnected everything. I also reset the GoPro. According to my estimation, the problem lies with the WLAN connection, which is established but is always interrupted. So when I want to control the GoPro via the iPhone or want to view the media, I am asked whether the WLAN should be connected. After confirming, nothing happens or in the case of the media view, an error message appears. It still worked 2 weeks ago, but since then there has been an update to iOS as far as I know. Can anyone help me?
