I basically started noticing when viewing a messages thread, sent/received photos appear with a white looking watermark ovular shaped thing. This occurs with iMessage and MMS. This only appears when in the 'thread viewing mode'; when I click the given pic, that watermark goes away. I do not recall seeing this up until a few days ago and I was wondering if this is normal/other people are experiencing it? See the attached screenshots for what I am referring to. I circled the watermark in red in the first pic and you can clearly view it in all 4 pictures in the 2nd pic. Thank you and have a great day.
