Since the Ui 3.0 and consequent Ui 3.1 firmware update on my note 20 ultra only some devices receive data through the hotspot from my phone. Whilst not a life changer in general, my VW 2019 navigation display also doesn't receive data although clearly connected to the hotspot. As the map on the navigation unit needs data connection to update traffic this is obviously not happening. No, I am not speaking about mirror link or android auto, I am just speaking about the seperate hotspot and data connection this navigation unit allows. Hotspot connects just fine, connection and IP address confirmed under connected devices, just no data. Anyone with a similar problem or even better a solution?
