Well, sorry for being such a moaner, but extending the voucher expiry date would impose absolutely no cost or actually any other side effect to Jolla, as the promotion has been long over, anyway. So the number of licences bought in that promotion is a constant and will remain the same, no matter if the voucher expires in June or October.
So I would say that it is a matter of merely doing a favor, especially in the circumstances of much delayed X10 III and VoLTE support.
I could not find the X10 Mk III cheaper than 400 Euros (brand new). Used units (very rare) are not much cheaper, around €350. Whereas the X10 Mk II in pristine condition can sometimes be found for around €200, or even less. So it is a huge difference, especially if one doesn’t need any gimmicks, just a solid device. And with the camera support and a number of other features of the Mk III being currently crippled/restricted in SFOS anyway, having to get the Mk III is actually paying double the price for nothing.
The most important factor is - obviously - VoLTE support. I have been holding on for so long with that second licence because I hoped that by the voucher’s expiry date you would make it clear for us if and when VoLTE would be offered for the X10 II, so that I could make a conscious choice whether to choose twice cheaper (and feature wise not much different) X10 II or pay double the price for Mk III. But VoLTE support for the X10 II still remains in the “some day we should be able to do it” phase, meaning that there is a risk in choosing the Mk II and possibly soon ending up with a VoLTE-less, i.e. useless, device. In other words, you’re kind of enforcing buying the Mk III this way.
I guess that majority of us users have been quite understanding for all the problems and delays, so why not repay us with such a merely a nice gesture that wouldn’t impose any cost to Jolla.
This is not about the cost of the licence (which I consider a way of supporting you, anyway), it is about +€200 to pay for the Mk III, which I would very much love to save if I only knew that the X10 would also get VoLTE. And I won’t know it by the voucher expiry date, if you don’t extend it.
