Payment Request screen says 'Press C to copy' but invoice is not copied

[AndreaDiazCorreia]

Summary

On the Payment Request screen, the UI says Press C to copy invoice to clipboard, but pressing C does not actually copy the invoice.

At the moment there also does not seem to be any alternative way to copy the invoice from that screen.

Expected behavior

• Pressing C should copy the full invoice to the clipboard.
• If clipboard support is unavailable in the current environment, the UI should not advertise the shortcut as working.
• There should ideally be a fallback way to copy or export the invoice.

Actual behavior

• The screen shows the Press C to copy invoice to clipboard hint.
• Pressing C does not copy the invoice.
• There is no other visible way to copy the invoice.

Why this matters

This makes it harder to pay the invoice from another wallet or app, especially when the user needs to copy the full payment request manually.

Suggested follow-up

• Verify whether clipboard support is broken or not wired on this screen.
• Add a visible confirmation when the invoice is copied successfully.
• Add a fallback action if clipboard support is unavailable.

Are you on windows? I always use C for copy and always worked on my PopOs?
