After 4 pages of discussion, still no official response from Flynax team. Not sure what is the problem.
I will arrange my schedule and spend this weekend testing on the new version 4.8.1 regarding the changing plan bug, and featured plan issue, addressed here in 2018:

Then create a new thread with a more catching title like this one:
CRITICAL FLAW: Renew upgrade feature doesn't work as it should
https://forum.flynax.com/showthread....k-as-it-should
I will try to make it as simple and as short and easy to understand as possible, with my limited English sadly. :(((
The reason why I haven't push this for years was because my site is pretty much only me and a few friends testing. If it's getting more popular this definitely will create huge confusion to customers. It's really time both Flynax and Flynax site owners look into this issue seriously.
