This email asks you to check, before the 6th, last month's home charging sessions. Review closes on the 6th at 7 am (Paris time), after which the charging sessions in the receipt can no longer be changed. Full schedule: "How and when is my reimbursement receipt generated?".
Where to check
Website: "Refunds", "Review your charging sessions" card, "Review receipt" button (open from the 3rd at 8 am to the 6th at 7 am). Direct link: https://app.volta-back.com/driver/refunds/review
App: the same card on "Home", "Charges" and "Receipts".
With automated reimbursement, the app says "refund" instead of "receipt".
What to check
Refund policy: charges within the refundable time slots are already included. If your company allows it, "Manage my leaves or exemptions" or "Manage my exemptions" appears (see "What are leaves and exemptions for?").
Charging log: no charge is included until you have marked it "To reimburse" ("Mark all to reimburse", after "Load more").
The receipt also includes charges from previous months that were not on a receipt. A charge counts according to its end date (Paris time).
A charge is missing or wrong
Tap "Report a problem": the chat opens with a prefilled message, which you complete with the date, the time and what is wrong. A charge from less than 3 days ago may not appear yet; a charge that arrives after the 6th goes into the next receipt.
After the 6th
Your receipt is generated on the 6th. If its amount is more than €0, you receive an email and can download it. With automated reimbursement, there is no document: see "How does automatic reimbursement of my home charging work?".
