I did a factory reset and now when I try to updaate, i get message package file invalid?
What you can do since you can't download apps for the meantime, you can download APKs by searching for them. Please try downloading and installing when connected on Wi-Fi. I read somewhere that downloading on Wi-Fi works even if they have the same problem.
I was trying to update apps, after reset first thing is to update apps but I couldn't even do that. I spoke with someone yesterday at Google and they said it was an issue with Google store which they were aware of and working on. They said at present, there is no fix for me but as soon as there is they would e-mail me instructions or a link to fix. Meanwhile they gave me a $10 Google credit. But I'm not able to add or update any apps in meantime.
