I've tried other edits of the DNG exported to PS/ACR, such as brightness. None of the edits is saved to the DNG which appears back in C1. I can only assume that the DNG export feature is there with the intention of saving the edited file to another location (not C1) and not to have the option of further edits back in C1, such as with a PSD export. PSDs do arrive back in C1 with their PS edits intact.
As an aside: I was going to send a support ticket to CaptureOne to see if I'm doing something wrong. But, I see that they now only accept support tickets with both Logfiles AND Screen Recordings attached. I couldn't be bothered working out how to do this.
I'm using version 22 and I have no intention of submitting to their new payment structure. I can see from other threads on this forum that I'm not the only one not happy with the direction this product is being taken. I get a lot more from Adobe for my tenner a month.

Ps. A workaround to my issue is to open a RAW file in ACR, apply Super Resolution, save it as a DNG and only then open it in C1. But, since it's possible to export a DNG from C1 to ACR, I'd like to be able to do it this way, if possible.
