Powerups won't add in business class

[Laurel Winkel]

I am paying for Business Class, but certain powerups won't add.  Specifically I'm trying to add the Time Tracking and Reporting powerup, but others won't add either.

Had a similar problem yesterday. When adding the power-up it gets immediately removed. It worked for me to switch from browser (Chrome) to the app.
