I noticed on a device that the Play Store app didn't work until I inserted a SIM card: is this just a bug or does the Google Play Store app requires a SIM card being present?
Background: I've installed LineageOS + OpenGApps Nano on a Nexus 5 device (without a SIM card). Almost everything worked as expected, including the Google account creation.
What didn't work was the Google Play Store app, though. When going to the 'My apps' sections, there was just an endless checking for updates/connecting animation. Installing apps wasn't possible. Clearing the cache/app data etc. didn't make a difference.
What helped was this: inserting a SIM card! After that and clearing the app data/cache again, the Google Play Store app worked as expected.
