Changing preview mode of one note changes mode for every note

[amarendra]

Version: 6.1.2 build 270 Latest iOS

Description

If one note gets its "preview only" toggled ON (i.e. cannot be edited by just one click/touch - i.e. the crossed eye icon showing) - all other notes also go to "preview only" mode.

And vice-versa - if one note gets "preview only" toggled OFF (i.e. can be edited now - i.e. normal eye icon showing) - all other notes also go into "edit mode" mode.

Feature/Fix

Saving preview mode or editing mode for every note separately.
