I can share my knowledge on this subject.
You can think of DA points as the RL's own currency.
When you buy DA points, you can use these points in all stores. If you have a coupon and after using your coupon, you can pay the remaining balance with DA points.
However, you cannot return products purchased with DA points.
But separately, you can store your DA points for use only in the marketplace, and you can use your credit card in other stores.
There are 4 stores but there are 3 cart systems.
1- Software and Content Store use the same basket.
(You can pay with DA points or credit card.)
2- Actor Core sells animation and Actor core characters and uses a separate basket system.
(You can pay with DA points or credit card.)
3- Marketplace uses a separate basket system and you can only pay with DA points.
I've had the problem of submitting tickets for support a few times.
My guess is that if you wait too long on the support page, there is a timeout. For this reason, you can try to send your message again by preparing it before opening the support page.
Another possibility is if they use secret captcha (I'm not sure), you can try to send a ticket after logging into your Google account.
You can get a new IP number by turning your modem on and off.
If the product you produce is a game, AR or application and you earn a fee from it in any way, even a one-time fee, this will be commercial use.
Licenses do not vary by market.
If you are buying products such as hair, clothes, characters, they have extended licenses.
The standard license is sufficient for the content included in the program, for products such as animation and props sold in stores.
I haven't tried it but for now there is no option to upgrade the standard license to the extended license.
