Is it only me having Wi-Fi issues on the iPhone 15 Pro Max with the latest few betas? When it's close to the router, it's OK, however in an adjacent room the signal is reported as low, there are problems opening pages, the iPhone often switches between Wi-Fi and 5G, and Speed Test reports awfully slow speeds. On my iPad Mini 6 with the same beta, there are no issues at all, the signal is strong, the speed is high. This started with some of the recent betas, maybe with dev beta 7, maybe earlier, not sure, but still not solved in dev beta 8. I tried everything, forgot the network and rejoined it, reset network settings but it doesn't help.
