1. Force stop the app
2. Clear the app data

||| This is not the same as clearing the "cache" or uninstalling and reinstalling the app. Neither of those tends to work for users affected by this bug.

3. Open the app again

If the app does not open correctly, or you have trouble with these instructions, please contact support.

# Frequently asked questions

## Videos don't play at all

It's likely an issue with the video host Vimeo. Please check https://help.gregmat.com/en/article/why-are-videos-not-playing-1kozdlf/ for what could be causing the problem.

## I can't see PrepSwift

Did you subscribe to the PrepSwift add-on? It won't appear if you didn't - you'll need to upgrade by going to https://gregmat.com/pricing. If you are sure you did however, contact the customer service representatives.

## I only see limited content (such as the first 10 days of the vocab mountain)

This is because you're on a free account and haven't subscribed to GregMAT+. Once you subscribe to GregMAT+ and reload the app, you should be able to see the other groups and videos. 

## I can't see GMAT or new TOEFL content on the app

The app does not support GMAT or the new TOEFL (toefl.gregmat.com) at this time; only GRE.
