Hello Michael Gernaey,
Many thanks for taking your time to address my problem.
I have 6 tables that I created as part of a power app within "Dataverse for Teams". One of these tables is named "Data_Sets" (see previous image attachment in previous post). As you requested, I navigated (within
https://make.powerapps.com/) Solutions => Default Solutions (see attached image A1, I could not find anything called "Default project") => list the tables associated.
I do not recognize any of the listed tables. They seem like MS generated data structures. My table "Data_Sets" is not included in the list of tables (see attached image A2).
As best as I know I am in the correct environment, as I only have one environment.
How did I create this app? It was created through "Dataverse for Teams", which is basically done by going to Teams => left panel buttons => selecting "View more apps" => "Power Apps".
From here I created my app "Database" (see attached A3). I could create a new app with the "+ New App" button, or continue to work on my existing "Database" app by clicking on the link, which takes me to the app builder.
I know there is some differences between "Dataverse" and "Dataverse for Teams", so possibly this is the issue?
