Just as the title says, my old iPhone 4 can load the Rune Audio UI almost instantly, yet on my newer iPhone 6, it never loads. The arrows just keep going around and around, not doing anything.
It doesn't matter if my iPhone 6 is connected to wifi through 5G, 2.4G, my router or my wireless extender. The iPhone 4 will load no matter how it is connected to my router, directly or through the extender.
