there is a bug in RB7, actually a modified continuation of a RB6 bug. It appears in a different way between the two versions.
This bug is generated by Apple own iOS and macOS clients (both latest versions) and not tested with other email clients.
- When deleting an email with Apple mail (iOS or macOS clients) in RB6 web clients those emails are not moved to trash but remains in in their original folder (in this case was Inbox) and the whole line containing email sender, subject and date is striked through (attachment RB6)
- When deleting an email with Apple mail (iOS or macOS clients) in RB7 the email disappears from the Folder but is still counted in the totals of each email folders (attachment RB7)
