I am having the same issues as Fredrik.
1. When I start my app my consent status is "UNKNOWN" when it should be "REQUIRED", since I am based in EU. If you are outside EU the status should be "NOT_REQUIRED".
2. I cannot get the consent message to show.
3. No ads will load if the status is "UNKNOWN"?
4. The "Set personalization" action still works and changes your consent status. After that ads will load fine.
5. Also what does the "Show consent message" action really do?
Googles documentation says we should:
1. Request the latest consent information.
2. Check if consent is required.
3. Check if a form is available and if so load a form.
4. Present the form.
Is 1-3 done when the app starts? And then we just show it with the action?
These are some of my observations so far. :)
