I am a Bedrock Edition addon developer. I also own a Realm on the side which is currently in a testing phase. I am trying to push a bug fix so I changed the packs manifest for the version from the current x.x.0 to x.x.1 and after doing that the pack did not upload and instead just said applying packs and did absolutely nothing except slap the version onto the pack cache so that when I try it again it thinks x.x.0 is x.x.1 even though x.x.0 is entirely different in file structure.
I believe this is happening to me also - i have corrected some issues with my pack but now it is refusing to actually replace the files even though it is uploading and saying it has - i know it isnt because the same issue that has been corrected is still happening
