I connected the 735xt to my laptop and already did all your suggestion. Then the system upgraded only today, but the last 6 days are lost. Plus automatic upgrade of the watch started and now the only language available is English, instead of having Italian, like I am. This is ridiculous, is getting worse after doing all your suggestion. Upgrading manually is not possible, the folder activity is empty. Freaking ridiculous. Now how can I get my old data. The watch shows me the steps history but doesn’t upgrade the GC on the phone and neither with the laptop. I want my data back. Yesterday was everything fine.
