Hi, I'm on playfulgod's Kitkat ROM on Galaxy Nexus.
Since I wanted to have two Maps (changepnp and stock) in parallel so that I can make use of "My places" feature with the changepnp version, I followed method 3.
However, after authorizing the app two times and signing in, I have the following error message:
Logged in: (Null)
And when I close the app and re-run and try to sign in, the waiting circle icon loops indefinitely and I cannot access "My places".
Does anyone have a clue to this? Please help. I really need "My places" feature, but I don't want to just downgrade the Maps app because then I cannot click on "update all" any more..
** UPDATE **
I solved my problem by installing MapsD V6.14.4 (With BLUE Icon).apk:
