Please don't create multiple threads just because you didn't hear back in 30 hours.
This is an open source project that is supported by its developers as a hobby - if you are looking for a product with 24*7 hotline support, I suggest that you look for a different app.
Also, you posted twice, using the default start for a question, and both time didn't include one of the key pieces of information: which version of Subsurface and Subsurface-mobile are you using?
A few additional questions:
- I assume that you are downloading from the dive computer on Windows and that's where you have additional dives that you can't sync?
- can you start Subsurface again, try to sync to the cloud; make sure there is a checkmark next to the File->Cloud storage online entry; if there isn't, click on that entry and try again
- then grab the subsurface_out.log and subsurface_err.log in C:\Users\<your login name>\AppData\Roaming\Subsurface\following two files and attach them to a response here
please note that the paths are slightly different in different versions of Windows, and to make this more fun some of the path name component might be localized...
Thanks
