Troubleshooting

Magic link login fails or loops

• If the magic link sends you back to sign-in, it likely expired. Request a new link and use the same browser/device.
• Clear third-party cookie blockers for syncpostly.com.
• If Turnstile fails, refresh the widget and retry; switching networks can help.

Instagram "400 Session Invalid"

• Originates from Meta and usually resolves after re-authentication.
• Refresh the Facebook Page connection that owns the Instagram account. If still failing, remove the SyncPostly app from Facebook Business Integrations and connect again.

Low TikTok views or cold accounts

• Warm up the account with a few native posts before scheduling via SyncPostly.
• Avoid posting identical content to multiple TikTok accounts on the same day.

Facebook Page connection issues

• Ensure you selected Pages (not profiles) during OAuth.
• Confirm you are an admin on the Page and that the Meta Business connection is not limited.

Instagram connection and posting errors

• Password changes or two-factor prompts can invalidate tokens; refresh the connection.
• For publishing failures, retry with a smaller caption or fewer mentions; some errors come from spam filters.

YouTube "Insufficient Permissions"

• The Google profile used in OAuth must have upload access to the channel.
• If you manage multiple channels, pick the correct channel in the OAuth dialog; then refresh the token in Accounts.

General playbook

• Re-authenticate the account, then retry the post.
• If the error persists, capture the exact message and post ID and send it to support so we can trace the platform response.
