Question: I have a SPO PowerApps form that redirects a user to a thank you page using the below script;

```
SubmitForm(SharePointForm1);Launch("https://tenant.sharepoint.com/Testing/SitePages/Thanks%20for%20Submitting!.aspx") Exit (true)

```

With this, the user should only be redirected to the Thank you window.

The thank you window appears as it should, but another window/tab opens with the allitems view of the list they just submitted to. 

I’m not sure how to keep this from happening. It should only go to the thank you screen. 
Has anyone experienced this? If so, I could use your help to fix this issue. 

Thanks in advance.

Answer: 
Privat channels always have their own SharePoint site. This is by design for security reasons. There is no way around it. Standard (not private) channels use the SP site of the team.
Each team in Microsoft Teams has a team site in SharePoint Online, and each standard channel in a team gets a folder within the default team site document library. Files shared within a conversation are automatically added to the document library, and permissions and file security options set in SharePoint are automatically reflected within Teams.

You can refer to the following articles to learn more about the relationship between the Microsoft team and SharePoint Online:

[How SharePoint Online and OneDrive for Business interact with Microsoft Teams](https://docs.microsoft.com/en-us/microsoftteams/sharepoint-onedrive-interact)

As Susan mentioned, if you delete this site or this library, the shared files and history of all users in this channel will be deleted, and it is not recommended that you delete this site.
