syncing videos and photos from iphone to icloud
My iPhone SE's camera and photo's apps behave strangely. The recent photos won't sync to the icloud as they are supposed to. Yet, one of the videos was surprisingly visible in cloud's trash: this was the one I deleted from the phone. There was reasonable amount of time for the videos to upload and mobile internet was always active (I never use wifi on my phone). How can I fix this problem?
iPhone SE, iOS 14
