What do you mean by not supported? I have a SaaS application installed and I need to add domains as registered customers. Everything is fine except for the trouble of adding new domains. Additionally, in order to support wildcard, I have to use DNS verification, which is another inconvenience.
I am a loyal user of aaPanel without any doubt. In fact, even though I don't actually need it, I will still purchase the pack just to show my support. However, if you want to be a serious competitor to cPanel, the details really do matter. It may seem like a small issue to you, but because of this problem alone, I am still unable to cancel my expensive cPanel license!
aaPanel is superior to cPanel in terms of being cleaner and providing faster response times. So please continue your good work but keep in mind that your competitor currently holds the largest market share and you are lacking in certain features!
