I can definitely confirm this issue for PS5 on Breakthrough. However folks, while I cannot remember what I’ve done now when it has occurred (about twice so far) please don’t reinstall or anything crazy like that.
I cannot believe I don’t remember exactly how I worked around this issue but I do remember that I’d spend some time swapping all of my attachments and I think I even went prone. I was trying things like that twice and voila, I was able to ADS again. This actually happened just last night (so annoying I cannot recall literally *the* action that caused it to stop and allowed me to ADS). Even after using Cas’ drone this can occur as well.
So again, it happened last night in Manifest, 2nd time I can remember this ever happening to me on PS5, Breakthrough, I then used + system to swap attachments for about 20-30 secs and I truly believe I remember going prone at some point and not too long after that I was able to ADS. I cannot remember if I did anything else after going prone. I did sort of keep trying to ADS after I’d swap attachments as well and I’d swap to my secondary or sidearm, swap it’s attachments as well.
The next time this happens I’m going to *slow down* and try every step slowly and then post results here. You definitely do not have to reinstall or anything, at least for PS5. Whatever I did to work around it, I’m confident it will probably work for PC as well.
