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.
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.
