(bug) Coach Profile Settings are not being saved

[CritiqalPete]

Coaches have the option to customize some features and we intend to expand these options. A coach should have to only perform this task once, and all future sessions should reflect that choice. Ideally, across all devices. This bug is only for one device and represents the MVP for this feature.

To reproduce:

1. login
2. Check the default positions of the Sessions and Teams tabs at the bottom. The left is the priority and first screen/view users will see after authenticating and in the primary flow
3. Select "My Profile" under the 3 dot menu
4. On the Profile Screen, tap the "home" icon
5. Choose the alternate default
6. The confirmation "HOME SCREEN CHANGED" appears
7. verify the change by tapping outside the modal and use the app for a minute, confirming the position of the tabs at the bottom has changed
8. log out
9. login again. It is not necessary to kill the app.
10. Check the positions of the tabs Result: They have reverted and do not reflect the customization

Expectations:

• the changes should persist between sessions, and also over time, even with new app updates, as long as possible.
• the customization choices should be stored by firebase so they can be retrieved and applied for that user, as needed

this bug needs additional detail to aid a developer:

• what firebase components are being used
• any useful output in the console when settings are being updated and retrieved?

presently this seems to be working
