Google Play not working after Update to 0.5.14 or 0.5.16
I am using Emteria on a Raspi Pi3B. First I installed Emteria 0.5.11 and the Google Apps (Pico). Emteria is a registered version. After that I updated Emteria to version 0.5.14. A few days later there was a further updated to 0.5.16. Now I realized that the Google Play Store does not work anymore. I tried to delete the Google account under accounts, but I cannot delete it.
Does anyone know what to do?
Thank you and kind regards
