(1) Conversation View
(1) Conversation view is threaded conversations - it is one of the main features of MailWise and we don't support an option to disable it.
(2) Grouping can be enabled or disabled - this means that if the feature is turned on - mails from the same source that you don't reply (such as birthday notifications, newsletters, offers etc...) are grouped into one email.
If this feature is unchecked - every email will appear as a separate entity.
In order to enable/disable grouping please go to "Settings and Accounts" ->General-> check/uncheck the box next to "Group updates emails".
