Ever since I updated my photon to 2.2.0 it has been failing to connect to wifi.
I had to add a 10 second delay after Particle.connect() on my setup because it just would give up and never connect.
Despite this I have to occasionally reboot the photon because it just keeps flashing green then cyan then green again forever.
I changed absolutely nothing on my code, except for a completely unrelated thing (inverted the logic of an LED).
I have several photons in production with paying clients on remote locations and if I update them and they never connect then I lost them (both the photons and my clients)…
