Newbie and a couple questions about the NEW Web EN

[chippwalters 1]

I'm an old Evernote user, and the last time (3 years ago) I tried it, it just didn't work well with my workflow. So, I recently downloaded it again, but needed to purchase it in order to check it out on my 3 main devices: 1) Samsung Note8 phone; 2) Windows Computer; 3) Google Pixelbook.

I had assumed, perhaps incorrectly, that after all these years, there was a mature product available. If possible, I would prefer ONLY using the NEW web client EN and not the Windows App. A few questions:

1. Is it true one cannot cut and paste (from my screencapture app's clipboard) in the OLD Web EN? But it works in the NEW Web EN?
2. Is it true one cannot create stacks in the NEW Web EN? But it works in the OLD Web EN?
