A security check expired or a form will not submit
Resolve verification, session, and too-many-requests messages.
If a form asks you to complete a security check, wait for it to finish before submitting. A passed check can expire or be used by a submission attempt; complete the renewed check before retrying. Also review highlighted fields and required agreement checkboxes if the submit button remains unavailable.
If the check will not load, check your connection and whether a browser extension is blocking the page’s verification content. Allow it for Wavshare if appropriate, or try another browser. Save your draft before refreshing or switching browsers.
For a session-expired or sign-in-required message, sign in again and reopen the page. For Too many requests, stop repeated attempts and wait for the displayed retry time, if provided, before trying again. Repeated clicking will not fix a limit or a missing permission.
If the problem persists, include the page link, exact error, browser, and action you attempted in a support request. Do not include passwords, verification tokens, or recovery links.
