I am using Field Service for Android application and i'm using default settings (environment create from scratch with no customization)

Following the process below, in some case "Refresh" button and "Show chart" disappear, and reappear.

1. Configure "Field Service Mobile" in "Offline first" mode (disable classic offline mode in app settings).
2. Make the first sync in mobile phone, wait until app be ready to use offline data
3. Close the app
4. Re-open the app : button "Refresh" and "Show chart" aren't showing up.
5. Navigate to an other table
6. Go back to home page : both buttons are available.

What are the prerequisites to see those buttons, is it a normal behavior ?

I made this suggestion after a MS support request.
