Thank you for this information! I can’t test until I get home tonight. I own an android and no problems with it probably because it allows sync upload in background. My wife owns the IPhone.
The strange thing is when I first made the share on the dashboard and connected her phone to the wd app, it started syncing all the files into the shared folder and I would watch more and more files get added while it was open in the iPhone app. This was not the case after I added others to the share folder with permissions. I did sign out of the account and resigned back in on the IPhone. I resigned back into the IPhone app, then I set the folder to the shared folder with permissions, I pulled down to refresh and waited for at least 5 mins while the screen was on. No files seemed to be uploading. I was even on my home wifi at the time where as before when it was working I was only on the sprint network. Afterwards, that’s when I went to settings and tried to re set the folder back to the folder needed because I thought I may have selected the wrong folder and it gave me the “incorrect password” error. So I went back on my computer, went into wd dashboard and made sure that the shared folder did indeed have permission for the username I had put in the app… I tried and tried again and kept getting the “incorrect password” error.
I did not have to much time to play around because I had to go to work. So I will try your suggestion and report back with info.
