Something isn't working
The sign-in link never arrived
Check spam first. Links expire after 15 minutes and work only once — if you opened it twice, request a new one. If nothing arrives after two attempts, the send itself is failing; tell us and include the address you used.
"That link has expired"
Either 15 minutes passed, or the link had already been used. Requesting a new one is safe and takes a few seconds.
I paid but I'm still on the free plan
Payment confirmations usually apply within seconds, occasionally within a minute. Reload the billing page once. If it has not applied after a few minutes, get in touch with the email you paid with — the payment record is kept, so this is always fixable and you will not be charged twice.
My progress disappeared
Progress is tied to the account, not the browser. Make sure you are signed in with the same email. Guest quizzes are never saved, by design.
A map shows "plan in progress"
The callout list and setups for that map are usable, but the interactive plan has not been drawn yet. Plans are drawn by hand rather than copied, so they arrive one map at a time.
Something looks broken
Send a message with what you clicked and what happened. The form attaches the technical details automatically, so a plain description is enough.
