Progress of my case so far (I have cut down the messages):
Aug 29th: “The package arrived yesterday, I had some issues to open it as I didn’t want to damage the box. We were able to reproduce your issue, we looked at it and found out, what’s wrong. HW colleagues fixed it. …”
Sep 14th: " It should be shipped at the beginning of the next week. Once I receive a tracking number of your package, I will let you know."
No info since, so probably it didn’t get sent beginning of this week. Things are for sure moving slowly on Turris side. Maybe they have actually replaced my module A (instead of just sending fixed module back) since Aug 29th, as otherwise I don’t understand where it has been all these weeks.
But there is time left to 1 month limit.
