Ditto. If you’re able to run an old version of the Android app, then you still have access to all of the Miku features. I haven’t found a similar workaround for the iOS app.
I run pi-hole and have a Samsung smart TV. How do I know that the Samsung DNS servers are being blocked? What prevents Samsung from registering new meaningless-sounding DNS names and continually pushing out TV software updates peddling “Security and bugfix” release notes?
