All billing activities, most importantly creation of invoices and sending them in email, were being done manually for the migration.
We are now going to make the billing system go into automatic mode. Depending on the status of your account, it may automatically create a new invoice, or send a reminder about an unpaid invoice. Or, if you have entered payment card information, attempt to automatically charge your card for any unpaid invoice.
If any billing errors were introduced during our migration, you might get an incorrect or confusing automatic email. If this happens, please do not panic. Simply notify us and we will make a correction.
