Byheart Design's Pattern Studio review for Photolock

I use PhotoLock to protect my original artwork, but I’m concerned about its performance impact. In mobile tests of the same collection page, the PageSpeed score dropped from 64 with PhotoLock disabled to 40 when enabled. A date-text overlay became the LCP element, despite visible watermarking being off. My earlier support request remains unanswered. Could you investigate this overlay and advise how to retain image protection without this performance issue?”
