Greasy Fork

doesn't work cause of your match line, must be:

// @match *://*.linkedin.com/feed/*

No, it works; this matched line code you made is exactly the same as the current match line code only difference is that you have a wild card character at the subdomain when there is no subdomain.

The only problem I see with the script is that if a user goes to linkedin.com and it redirects to the feed: the script doesn't kick in and only works after a forced reload. Otherwise, directly going to https://www.linkedin.com/feed/ works great.

First, we have this error at installation:

Second, directly charged with your supposed good adress and force reload, it doesn't work !

Oh, you're using ViolentMonkey; I'm on TamperMonkey so I don't get the same error. I think ViolentMonkey is just stopping the script from working: I honestly forgot there's TamperMonkey derivatives. I'll install ViolentMonkey and take a look into it, will release an update for the script later. Thanks for sharing your feedback.
