Using IPv4, the connections had no problem. Also, the ones from iPad including IPv6 were good. Before the upgrade, the app version was V1.0.20200407, which could establish connections successfully. # reconfirmed by manually installing the old version of the app. # The IPv6 internet connection from my phone is always quite good. On my router, I used tcpdump to check whether packets emitting from my phone were observed. But, no packet was found.
