I have tried many times to purchase lives, boosters, etc in the store. However, I always get the error message "failed to contact store". Can you help?
Which store are you trying to connect to (device/game)? Are you connected to internet with strong connection? Try turning off your device, restarting, connecting to wifi and try again.
Yes, I am able to access play store on its own and make purchases. I was on wifi but switched to data after it didn't work. It still did not work. I usually just use wifi. It is a very strong connection.
I am not sure if it makes a difference. But would would my county I am in (Bermuda) make me unable to make purchases? I have never had that issue before with other games. But I just trying to think of every possible reason.
Is this the first time making a purchase or has it worked in the past? What version of Candy Crush Saga do you have installed? (go to settings then apps click candy crush saga and scroll to the bottom) It sound more like a connection issue. I just tested on my S7 and was able to connect.
Did you download this game from the play store? You could make other purchases so do not think it would stop you here (I could be wrong and will ask someone)
