Why are my boosters all locked

Question

This morning I had plenty of boosters, now they are all locked. I tried updating my tablet, signing out and signing back in.

Wow this must be a new glitch because I never saw that before.  I am going to ask both of you to please do some troubleshooting because they are going to ask you to do that anyway.  Make sure to clear the history and make sure that you have the latest version of the game.  Then choose one of the links below to troubleshoot. @kichaa and @Fltan I need both of you to please write me back after doing the troubleshooting.  If it's still doing this then I need to elevate it to the Community Manager.
