Hi,
I would like to post some pictures in the Skypixel and select "Publish locally stored photos" but unable to find my photos, is there anyway I can access certain folders with this app?

Hello there. I appreciate your time bringing this query to us. You mean in the DJI Go 4 app? I highly suggest saving all the files coming from the SD card since the files that are coming from the app is just a cache file and there's no guarantee in regards with the quality.

I did create a folder in my phone and copy all the files into it but seems like the DJI Go 4 apps only access "Camera" folder only
I have to upload it from my laptop.
