@TomaszPoszytek : I successfully followed your instructions on https://poszytek.eu/en/microsoft-en/office-365-en/powerapps-en/importing-powerapps-package-as-a-sharepoint-list-form/ to import a modified PowerApps package to customize a new SharePoint list based on the same template as the original list.
Whether I modify the package to be on a new site (https://hecmtl.sharepoint.com/sites/CampusInternationalHEC2 instead of https://hecmtl.sharepoint.com/sites/CampusInternationalHEC) or as another list on the original site, the import works, but the data connexion is still the original and not the new one. Both apps are in the same Powerapps environment.
Everything I can find in the modified package seems to reflect the correct changes (list URLs, list IDs...), but I'm stuck with a connexion to the original list. If I create a new data connexion, it breaks the link to the SharePoint list and can't see either the old or the new, even though the data connexion is find.
Any clue about what could be wrong?
Thanks,
Frank
