Your comments

Just wanted to let you know that the app is working perfectly for me again – although I haven't changed any network settings.

Because the problem appeared after an iOS update, I always suspected the issue was with iOS and not with the app. (So I would not ask for a refund or credit, because I don't think it was your fault.)

Sure enough, after the latest iOS updates, everything is back to working fine. My conclusion is that whatever Apple accidentally broke, they have now fixed.

Thanks for your patience – it is a great app!

Hi Enrique,

Thanks for the suggestion. I was able to create the adhoc connection between Mac and iPhone, following the steps outlined. Both devices correctly showed connection to the adhoc network.

However, when I ran PhotoTransferApp via the adhoc network, it now returned error "no devices found."

Yes, no change. Same home Wifi network. I can switch between 2.4GHz or 5GHz, or between 802.11n only or 802.11a/b/g/n but it makes no difference.

As mentioned, I have reset the router, powered phone off and on, removed and reinstalled the app on phone.

Running on MacbookPro with OSX 10.9.5. Photo Transfer App v2.2. Following all steps as directed, the laptop reports it has discovered the phone and is connected to the phone. However, no thumbnail is displayed of any photos since the last iOS update. There are thumbnails of earlier photos (perhaps cached?). But if I try to select and download ANY photos, app returns error message: "There was an error communicating with the device. Please make sure that you are using the latest version of Photo Transfer App on the device and that it is connected to the same wifi network."

This is very unfortunate because the app was working great until the iOS update. I learned about the app from a Lynda.com course on using the iPhone camera and I really liked it.
