@flohack I have two OPOs, and both had this issue. The wifi switch disappeared after the update from OTA-5 to OTA-6. I've also installed OTA-7 on each of them, and the issue persists. Should I just wait for OTA-8?

btw. @Flohack I mentioned to you in irc that I don't need two OPOs. Would any of the development team be interested in having one? I would be more than happy to donate it.
