I've had the new TPG app instailled on my iPhone Xs for some time know. In the past i used to be able to get the app to perform a speed test of my NBN.
However, recently when trying to get the app to perform a speed test, it says it cant detected my connection, and wants me to test my connection. So i test my connection and it says it alls fine, but still cant perform a speed test on app.
I've uninstailled and resinstalled the app and that didnt help.
I'm using an iPhone Xs on iOS 14.4
Thanks for raising this with us, @Woofie.
We'll raise this with our Devs team to check on this further.
Meanwhile, you may test the speed via Speedtest.net.
Let us know if you need further assistance.
