If I’m understanding the commit message correctly, there’s a chance that this bug was just addressed: https://github.com/particle-iot/firmware/pull/1578
Unfortunately, from looking at the changelog, the bug at Electron power-on connectivity issues with 0.8.0-rcX doesn’t seem to have been addressed, so many of us have to stay put with 0.7.0. With luck they’ll backport this fix, since the original bug was from some three years ago and would thus have affected all final releases.
