[Bug] Unlisted surveys don't allow invitation by eMail #2285
Description
When a survey is shared "Restricted", i.e., adding every data collectors individual eMail address, the survey shows up in the app as expected.
However, data collectors added with their individual eMails do not see a survey in their app, if it is "Unlisted". They have to go by the link/QR code. This includes the survey owners.
