Bug Description

Repeatedly clicking/refreshing the funding page creates multiple invoices in LNbits instead of reusing an existing unpaid invoice or rate-limiting invoice creation.

Expected Behavior

  • Reuse existing unpaid invoice if one already exists for the same amount
  • Or implement debouncing/rate-limiting to prevent invoice spam
  • Or invalidate previous invoice before creating a new one

Actual Behavior

Each request to the funding page creates a new invoice in LNbits, leading to orphaned unpaid invoices.

Investigation Needed

  • Identify where invoice creation is triggered in the funding flow
  • Determine if there's existing logic for invoice reuse
  • Implement appropriate fix (debounce, reuse, or cleanup)
