Check the basics
Make sure you are using the correct app and current account details. Remove accidental leading or trailing spaces and check upper- and lower-case characters.
Confirm the account is active
If access worked previously, check the subscription status and any provider messages. Contact support if you need help checking your subscription or account access.
Avoid repeated guesses
Do not keep trying random password combinations. Contact the support team for help recovering your access. Never send a password in a support message.
Prepare a clear support request
Include the app name, device model, exact error, and when the issue started. Use the contact page to send your question to the owner inbox.
