Backup and sync, a plan to activate, a question about your data, something that does not work: write here, a person answers.
Before you write.
Should I send my timeline with the message?
No. Describe what you see; nothing about your health belongs in an email. If a JSON export is needed to reproduce a problem, the answer will say so and how.
What helps for a plan question?
The username of the account that should carry Backup and the email used at checkout.
