I am pretty sorry for the inconvenience caused to you.
We are trying hard to develop the new firmware for E1 zoom, but we don't know the specific date.
If you are willing to wait for us, we can provide a partial refund to you for compensation.
Is that ok for you?

It's not clear to whom this was directed, but if to me please suggest how much refund is proposed. My purchase was from reolink.com, order #1102496, 24 Sep 20. You should have my contact info from the order if you wish to contact me directly.

As for firmware question: I can't imagine this more expensive E1 Zoom model has less firmware space than E1 Pro cheaper model.
The Preset functionality was part of the sold hardware in the past and advertised.

I agree, but it does have other features (zoom) that would consume memory space. Perhaps our desired functionality was removed to make room for other changes that they deem higher priority. Again, it's only speculation but why else would they be struggling to incorporate such a basic feature that was previously there?

This is only speculation but it sounds like they have a problem with available firmware memory space on the E1 Zoom. If so, reintroduction of the feature may not happen without removal of other features, if at all.

Are there plans to add presets to the E1 Zoom? If so, what is the timeline? I had no idea it didn't have this basic functionality, and I'm deciding whether to return it.
