Thanks for the info! I recall reading about that before, but forgot about it.
With respect to your question, I didn't post a log from iw dev after a reboot, but ap0 does appear after reboot.
Before proofreading my post, I originally included output from iw dev at the end to show everything working, but realized output from ip addr was more useful, since it shows actual network addresses and up/down connectivity. I may just re-add that for clarity. Thanks!
