How do I stop a web form submitting twice when somebody double-clicks the button?
Our answer
Disable submit immediately after first click and implement server-side idempotency for each submission token.
Why this approach makes sense
Device software, permissions and connected services change how a feature behaves; use settings for the actual model rather than a generic workaround.
Before you try it
Verify the relevant device and account permissions, and make changes one at a time.
