The widgets on the left of my screen only shows Osmo apps. What should I do?

If only Osmo-related games are showing on your widget, it could be because there is excess data stored in the launcher. You can solve this issue by clearing the app data as follows:
 
1. Go to All Setting

2. Select Apps

3. Click on See All Apps

4. Select BYJU’S Launcher

5. Select Storage and Cache

6. Click on Clear Cache
