I'm jealous that yours is still working, and I'm looking forward to getting back in the fold. My Fitbit Versa that I finally got after the acquisition is definitely spiritually related, but after Google bought Fitbit and got involved it became terrible with bugs.
Unfortunately it isn't quite everyone, it appears to only be folks affected by the overheating issue and you need to have all the original accessories. I replaced the strap because the one it came with tore.
