I did have it stop working after a short while and had to bounce Olas to get it working again. Not sure what that's about, but will continue to rest.
Discussion
Same here
It does seem to continue happening, reactions or comments work one minute and the next they don't. Bouncing fixes it temporarily. What's odd though is that I can see the activity in Amber though. The nsecbunker is seeing it. The comments or reactions never show up in app. 
Pablo is on the case. Fix tomorrow.
