Hi! I understand you're having trouble sending a photo to your Uhale frame— it gets stuck at 90% and then freezes and fails. Let's see if we can get this sorted out together.

To start, could you tell me if this happens with all photos or just specific ones? Also, are the photos large files or standard-sized?

Meanwhile, here are some troubleshooting steps we can try based on common causes:

1. Check Wi-Fi Connection: Make sure both your Mac running OS X 10.15.7 and the Uhale frame are connected to the same stable Wi-Fi network. An unstable or mismatched network can cause uploads to freeze.

2. Restart Devices: Power off your Uhale frame and your Wi-Fi router briefly, then turn them back on. This refreshes the network and can resolve temporary glitches.

3. Photo File Size and Format: Verify that the photo complies with the frame’s supported formats (usually JPEG or PNG) and size limits. Large high-resolution photos can sometimes cause upload failures or freezes.

4. Try Smaller or Different Photos: Test uploading a smaller photo or one taken with your device’s default camera app to see if it completes successfully.

5. Clear or Reinstall Uhale App: Sometimes app cache or data gets corrupted. On your Mac, if you’re using the Uhale companion app, try clearing cache or reinstalling the app.

6. Ensure Frame is Properly Paired: Confirm the frame is properly bound or paired within the app.

If you’ve already tried any of these, please let me know so I can suggest more targeted steps. How is it looking so far? Would you like help with any of these steps in detail?
