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: 
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.
Despite not knowing any german, this is a screen shot of deleting a site and not a page.
Secondly the 'Delete site' is beneath the sentence "alle websitee...". I cannot comment if it is there or not since the screenshot stops exactly before.
Third the 'delete site' link is also available in Site Settings (which is your 'alle websitee...') under "site actions".

If you cannot get to Site Settings and see this command it means you are not site owner or the site owner permission level assigned to you as been modified.
