Where are missing features in Snote gone?

[AC Question]

Hello, I have a galaxt note 4 and after the marshmallow update, a load of features have now disappeared from snote. These features are not in the downloadable extension packs. They include:

Not being able to quickly share or delete notes in the preview sections
Not being able to set a photograph taken with the camera as background in snote
Not being able to take a picture with a user defined shape
Not being able to apply photo effects to imported pictures

I have also noticed that the templates are all gone.

Has any other note 4 user come across these issues since the update? My note 8 still allows me to use all these features.

Thanks
