Do you mean when connect vpn through mobile network to the ATP/USG, it works. However, it doesn't work if connect via home ISP line(PPPoE,IPoE, Cable modem, lease line…etc) ??

If your device is managed by nebula, you can pay from nebula portal directly, choose "License & inventory" Or you can buy it from zyxel's marketplace portal instead https://marketplace.zyxel.com/ I don't know what's the platform you shared but I think the official one is more reliable no doubt

I have similar symptom on my device and Zyxel told me not to login to the device GUI after rebooting the device and they will release a patch for this issue soon. Try not to login to the device after rebooting and see if it helps

I don't think so, you'll need to add external zyxel ap (managed by USG20W-VPN) to support this
