Onboarding screens at ap startup:

Things to note

• To test this feature, uninstall then re-install app to your device to force Disclaimer and then Onboarding screens to be presented.
• Disclaimer content updated by moving some to onboarding screens and current version is 7
• Disclaimer screen at app startup style matches the onboarding screens at startup
• Possible first screen combinations are:

1. Users first run after app install, screen shown are: Disclaimer, Onboarding and then Home screen.
2. User has app installed then upgraded the app AND Disclaimer has changed in the new version, screens shown are: new Disclaimer screen only (onboarding screens NOT shown again).
3. User is using the app normally, screens shown are: Home screen only.

• Disclaimer and Onboarding screen urls are present for reference only and NOT enabled as links, so as not to encourage users to go to those pages whilst onboarding into the app.

No one around, but @greggmiller has reviewed this change and approved. I've also tested on many devices and configurations, so going to merge so we can produce Beta 4.
