Deleted files taking up iCloud space again
About two months ago I deleted around 400g of files from iCloud and downgraded my plan from 2T to 200G. Things were fine at that moment. My usage was correctly updated.
And a few days ago I found that my iCloud is full. I checked the usage on iCloud.com. The 400g files seemed to come back on its own and are taking up all the space. I looked around for the files. I checked the "Recent Deleted" on iCloud, and the "Restore Files" in iCloud Setting. Nothing in both places.
Currently, I only have about 2g of files on iCloud. All the ghost files are stopping my devices from syncing. I have no clue what's going on. Please help.
