Hi @Lady_Sarina, @Lola_Pop ,
since the last update, my old Android device (Android 6.0) seems to be no longer supported. When I want to open the app, I get the message: Candy Crush Jelly has been terminated. I then have the buttons "ok" and "report". Report does not work, there is no response. With "ok" nothing happens either. I can no longer use the app. The problem I have is, I have accumulated the most boosters there and always use this device to consume the boosters. I know they are not transferable to other devices.
Unfortunately, when updating the app, there was no indication that older Android versions are no longer supported. Otherwise, I wouldn't have updated and used up my boosters for old levels in competitions.
Maybe you could give a hint in the community if other players are also affected. Unfortunately, I did not find any hint, not even on the Internet.
