@BigMcGuire Thanks for your support. Yeah it's sad, but I knew it will happen, I'm trying to not bother too much. Having a father like that also didn't help much
. I'm doing my best and if one doesn't understand, I can't do anything about it. I try to remind myself that most people actually have no clue what goes on behind the scenes.
About the Mac App, I hope that exactly these problems you mention I have fixed in the today's update version 2.9.7. I couldn't reproduce it myself, so maybe it does the trick. But I'm also at a limit here, the iPad to Mac conversion thing in Xcode (called Mac Catalyst) isn't as good as I thought.
About the servers: On the 3 free ones I have unlimited traffic, the others don't. So I have to monitor them.
@Apple_Robert: Yeah but how, if Apple doesn't allow me to gift the In-App Purchase? Should I PayPal them? Through my code it also isn't possible to distinguish.
About the Premium issue, are you also one of them who bought the combined lifetime unlock one?
