Wi-Fi sync not working without both usbmuxd and netmuxd running at the same time.
For some weird reason, without usbmuxd running, AltServer refuses to run completely (Device not recognized by altserver)
[2023-01-06T17:21:00Z ERROR netmuxd::heartbeat] Failed to create heartbeat client for udid [x]: UnknownError This seems to be the error.
Nvm, the issue seems to be persisting even with both netmuxd and usbmuxd enabled.
I connected my iPad to the Raspberry Pi using a cable and started netmuxd. It runs perfectly, but this error occurs when I don't connect them during startup.
