Lock exposure? – Iriun Webcam for PC and Mac Review

I think I might have to revise my review. I upgraded to pro for one feature - the ability to lock the exposure. I can’t seem to do it on my iPhone SE 2020, iOS 14.14.2. I see an icon that looks like the one for exposure (a half black/half white “sun”) but can’t see any changes when I tap it – exposure varies as I move the phone around. Frustrating because there is no way to contact the dev – I looked around the web site, can’t find a link with an email, nothing. Time for a refund I guess.
