Brand new vivoactive 5, worked fine for 2 days but now syncing of any activities with the app has stopped working entirely (steps, sleep, etc, do sync fine though). Tried trouble-shooting approaches as outlined here and on other sites, but apparently manual upload is the only way around/the only way it works. Is there any hope it'll get better with time, that this is just a temporary glitch? honestly, this is so inconvenient, and it defeats the whole purpose of a sport watch (for me, at least) so I'd rather try and get my money back, if possible. Unless there is reason for hope... Any input?
