Sharing an app prototype and a database in this community?

[Thulium]

Hi.

I help an ngo and made my first attempt with Appsheet today. The result is very promising.

Of course, there are questions.

1. Sharing with the community
   How can I please share an app prototype and the corresponding database here in the community?
   I have "deployed" the app. The link is: https://www.appsheet.com/start/0d9b20e7-a481-429a-bc9b-95e8fc7a329c 
   If I am logged in as the owner, I can open it as expected.
   But when I am logged in with my private Google account, I get an error message "Access denied".
2. Initial value
   For a column "DateOfEntry" I have set for "Initial Value" : _ROW_TIMESTAMP
   Nevertheless, this value is not automatically entered when I add a new data record
3. Automatically enter logged-in user
   For a column "Reporter" I have set for "Initial Value" :USEREMAIL()
   That works. But I need the user name.
   "Initial Value" :USERNAME()
   That does not work. Is that known bug?
4. ToDo/Done
   The column "Done" ist set to type: "Yes|No".
   How can I ensure that "No" is pre-entered and how can I change the word "No" or "Yes" to the corresponding words in German?

I would appreciate your help : ) Thank you.
