I am your client, there was a little problem,
I can not download charts for android from the Play Store on the phone (but it’s not convenient, the display is small), but the tablet does not see.
How can I get apk file
Thank you. Best regards, Gennady!
This suggests you have android os <5 and cannot run it. The only solution is to update os or buy new tablet. (Google Play and App Store only show apps that are compatible with the device on which the App Store is running)
