For the record, @tortoisedoc @PeperJohnny @ivanpetkov13 @makarch @vknecht and anyone else who may be interested:
I’ve put the topic up for discussion in the community meeting this Thursday, 22 April, to find out if Jolla would be willing to come back on their decision regarding the Xperia X. I can’t attend the meeting personally, but if any of you is available and wants to add something, please do partake in the discussion. Regardless of Jolla’s answer, I hope this will provide closure.
