It sounds like there’s a keyboard mapping issue between your iPad's Magic Keyboard and the Windows app, especially with the Swiss German layout. The “@” symbol using AltGR (or Shift-Option) might not be translating correctly in the Windows app. Since it works with the Jump App, it’s likely a bug or limitation in the Windows app's handling of the Magic Keyboard. https://www.banuba.com/blog/full-guide-virtual-try-on
In the meantime, you could try these workarounds:
- Use the on-screen keyboard in Windows to input the "@" symbol.
- Temporarily change the keyboard layout in Windows to one where the "@" symbol can be accessed without AltGR.
- Check for any updates to the Windows app, or consider reaching out to their support team for a fix.
Hopefully, Microsoft addresses this in a future update!
