You can add one more to your list. My plugin had been on sale for less than a day when I got my first email from an irate customer that did not receive their plugin. It took me another few days to figure out what was happening, but it seems they did not use the email address that is linked to their Adobe ID.
I’ve added a note about this to my marketing material, but this won’t stop this from happening again, and when it does, I am the one that gets the irate email. I am the one that loses the trust of my audience, which I’ve worked hard to build.
Adobe’s position of pushing this down the priority list is, in my opinion, completely irresponsible. We are both taking money from people for these plugins. Knowing about an issue that causes the product not to be delivered and doing nothing about it is a complete inexcusable fail. You wouldn’t see the little guys doing this, because we care, and even though we often lack resources, we work hard to overcome this kind of obstacle. Working with a giant like Adobe shouldn’t put developers and our audience in a position to immediately hit such a fundamental fail-point.
Please consider reprioritizing this. It’s not as insignificant as you’d like to think.
