I think the thing I would do is check it on a different WiFi to rule out some weird compatibility issue.
Not as daft as it seems. My S20+ runs dual SIM on Vodafone and O2. Vodafone works fine but I found O2 was not kicking in. After some messing I found that it would not work on the 5G band but was fine on 2.5GHz
Admittedly my Hub 5 is renowned for compatibility issues with Samsung and that is what put me on to it.
Works great on my daughters SKY router at 5GHz.
That's why it is good to check as it takes one item out of the equation
