Subscription, Trial, Subscription Time

Alright, so I'm really confused.

Some time ago I started playing as a Free Trial. Three days later I bought ARR for 10€.

My Days Remaining on Subscription went to 30 after that and started decreasing, as expected.

First Issue: my Total Days Subscribed is still at 0.
Second Issue: I just got an email saying my free trial is about to expire, precisely on the day my subscription ends.

What is going on here, am I subscribed, am I not subscribed? The trial is for 15 or 21 days and I'm closing in on 30.

Total days subscribed counts toward your Veteran rewards. This number reflects the number of PAID subscription days. For example, if you buy two months in advance it will say 60 days even if you have only played for 30.

So I assume I have 0 Days subscribed because ARR includes a FREE subscription.
That makes sense.

What still doesn't make sense if the email I got, saying my trial was about to end.

I think it gives you the opportunity to complete your free 2 week trial even after you purchase the game. The trial has a lot of restrictions though so I know there's an option to upgrade right away.

The free trial email basically didn't check to see if you were already subscribed or not. It probably just automatically sends when it's nearly the end of the trial. If your days are counting down from 30 and you added your licence code then yes you're all setup and you're on the 30 days free that came with the game (the rest of the trial time was voided).
