Instead of saying Linkedin get it together, give me back my impressions which will never come back, i am also pissed btw but we can do two things:
Whine, and receive pity comments or
Get a Linkedin advertising business acc and run two types or campaigns which bring impressions almost for free.
1) follower
2) right hand ads
I bet you can spend under 100$ a month and get some additional 10k impressions.
