Since a lot of people is suffering this (I stopped counting at 14 persons five days ago) and messages are scattered all over the forum and making a mess of the official release thread, I’ll try to link useful responses here, for reference.
You don’t need to install any particular app (UnifiedNLP, microG) or mod (tingle, Xposed) to suffer the bug.
