Hello,
I’m sorry to be a bit late to this discussion! Jonathan explained it correctly: you should keep the release-version and release-date the same for your updates, only increasing the version number. I agree it’s not very intuitive, but I hope it’s clear now, and you won’t encounter any issues with future releases.
The only point I’d like to add is that setting a new release-version/date also resets trials . As a result, increasing the release version with every update essentially allows some sneaky users to continuously access your plugin through trial periods.
