Like many other people I had to uninstall and reinstall after the 1.10.2017 update.

Unfortunately on a mobile device you can lose all boosters at any time.  You can read about it here:

I don't understand how your company created an update which seems to only of benefited your company because a lot of people lost all of their boosters with no solutions. You either need to look at your IT department for their inability to create updates without effecting people who have been playing the game without issues before the update or look at the motive behind the update!
