Interesting finding here. Our two Huawei cell phones had a problem with the latest Stuff app update that happened a few days ago. It would take 15-17 sec to produce any Stuff data on the screen. Just had a spinning circle.
Emailed their support team and the long and short of it was a router reboot fixed it.
It worked fine on cell data and everything else seemed fine. Speeds as expected etc.
Maybe routing tables needed re-setting?????
