I am not surprised with your observations. I have 9.7 running on Simulator and I find it difficult to adjust to the new experience, may be I am hooked to the classic view and don't have patience to view/read through it yet. I have seen few posts where users have raised concerns about certain options not visible or available, however on switching to classic view it does. Thank god, atleast the 'classic view' is still maintained. I will try to view snapshot policies in my lab (as you observed) and let you know how I find it.
I installed a few systems with 9.7P3. I saw several GUI issues (export policies with more than one IP not working, editing initiator groups could lead to lost of initiators... ). Recently NetApp released P4 which fix a few issues. Take a look to see if this is listed.
I keep switching to the "previous GUI" to do a lot of tasks since this new experience lacks a lot of basic capabilities (IMHO).
