AR750 tethering to Samsung s10

New user just got a GL-AR750 travel router. Up and running. I can connect to internet via cable and WiFi repeater mode but not by tethering. Phone is a Samsung S10 set up as hotspot and USB tethering enabled. Connected via usb. Firmware is version 3.026 on the AR750. Phone is seen by AR750 as ether 2.
Attempted connection and software just spins and then times out. Any suggestions???

Because we don’t have Samsung S10 for debugging now, we are looking for a Samsung S10 to debug this problem. We will inform you in time if there is any news.
