Cannot input observation to an invited project using phone app

#1

I have an invited project, invited one person who cannot input an observation using the phone app but can using a desktop. Please advise.

#2

Without specific examples such as the project name, screenshots of what the user is seeing, and other information, it’s difficult to diagnose what might be happening here. Can you please share those? If you don’t want to share them publicly, you can email help@inaturalist.org.

It is an invited project only
When I go to add an observation to the project on my phone comes up from iNaturalist but this one above. I am a member.

Typo above: should be 'When I go to add an observation to the project on my phone every other joined project comes up except for this one above. I am a member.
