It seems to be happening several builds before, but on mix 2 I don't get the 5ghz wifi network. Changing channels did the trick but it's annoying as now my other devices don't detect it, note that with the stock build I had access to it like every device in home. I tried magsik modules, anything and I can't figure out what's wrong.
No it hasn't - only certain channels that are illegal in your specific country.5ghz wifi has been limited
5ghz has been disabled for EU countries. Check the MIUI forum
The same happened to me with a vocal message, maybe a WhatsApp error server side (?), remade the vocal message and sent normallyYesterday on my MI 8 SE V8.12.13 when trying to send a video of a dessert that was doing Whatsapp reported "the format of the file is not supported"
