I recently found myself stuck in the same situation, posting every Tuesday at 8 AM and getting maybe three reactions. Things changed when I focused less on posting frequency and more on leaving thoughtful comments on five other posts before publishing my own. This livened up my feed in a way I never expected.

About a few months ago, I stopped monitoring algorithm changes and began considering reach as a separate issue from content quality. If a post isn't seen by the right people, it won't be effective. One practical step is to get your existing network of likes to like it early on so the platform considers the post worthy of sharing. For example, you can get free likes on LinkedIn here https://upvote.club/linkedin
