Check file size and connection
Large photos can take longer to process, especially on mobile networks. Try again on a stable Wi-Fi connection or compress the photo before uploading.
If you are uploading many gallery images, add them in smaller batches.
Try another browser
Some in-app browsers handle photos differently. If upload fails inside a chat app, open ChungDoi in Safari, Chrome, or your phone's default browser and try again.
