I have 160 dives downloaded (uploaded?) to the Shearwater Cloud since February, 2020. These were all downloaded from a Teric (v16, 17, 18) to Windows Cloud (last version, 2.6.x). At that time, everything was working on the Windows desktop, and on tablet and phone.
I upgraded my Teric to v19 and my Windows Cloud to 2.7.1. After the changes, the Windows desktop no longer displays the calculated SAC, but accurately gives start pressure, end pressure, and gas used. It displays the SAC as 0. Some of the dive graphics still display SAC during the dive, while others have a flat line at 0. The tablet has the same errors my laptop has. Interestingly, the phone displays the calculated SAC and a normal SAC graph for every dive.
I sent an email to Shearwater a week ago, now, with 2 follow up messages. Uncharacteristically, I have not heard back yet. I hope to hear back from them this week.
I wonder how many others have had similar problems, thought maybe I was alone until
