By setting up a new Job Feed as described here you'll fine-tune your job searches to show the better results that match up with what you’re looking for.
Your saved searches also influence your Recommended jobs and saving more related searches may improve the recommendations overtime.
I am having the same problem. I did the recommendations and still the same. I only see an hour ago posts in my job feed. But using the app in my mobile phone I can see new posts.
I checked your feed and can see that new jobs are listed on your Find Work page. This one below was posted 15-minutes ago.
Please know that you should also be able to select which feed you want to check by clicking on the options I have annotated above.
I checked this for you and I was able to see your job post and there are three proposals already on it. Please clear your cache and cookies and try using a different browser. If the issue shows on your end after this please let us know and our team will assist you further. Thank you!
