After FW update, no apps download

I updated the FW of my EU-JY-UOS03N4G (ordered july 2019) and now I cant download apps
in Google Play. I get the message, that it is awaiting download, and that continues to stay.

I have confirmed that I DO have internet connection in Chrome.
I have tried to use the Internet connection on my phone via Wi-Fi

I hope you have a solution.

best regards
