LinkedIn's algorithm seems to be related to how active you are. One step you could try is reaching out to any recruiters you may have added over the years and ask them if they know of any open positions you might be a good fit for. If you haven't added any you might be able to look in your feed to see if there are any advertising jobs and reach out to them from there.
I know LinkedIn and recruiters get kind of a bad rap but I really like working with them over applying the old fashioned way.
You get more phone calls but it beats filling out forms. If you get multiple recuriters working on your behalf you can setup situations where you try to interview for lots of companies at once in batches. If you're currently unemployed and have the time for that, some companies will eliminate time consuming steps in their interview process to hire you before one of the other companies does.
I haven't looked in the last few months but this is most of my strategy for finding good jobs without having to bother with annoying things like job applications or too many interviews.
Long term an additional thing you can do to boost this is continue to add recruiters on linkedin even when you're not actively looking.
I don't enjoy the job search, so I let the recruiters do it for me.
You can be pretty straightforward with them too because they're incentivized to get you a job with commissions. You might be surprised with what they come back with if you tell them very explicitly what you're looking for (money, remote, type of interview, etc). Of course the more recruiters you work with the more likely some of them will be able to turn up these roles.
I also like this system because it ensure you are only working with companies extremely motivated to hire. At the point where a company has hired an external recruiter, they have already spent thousands of dollars to try to hire you, failed, and now they're spending thousands more in commission to send someone out into the wild to find them someone they can please hire.
One last thing I'll throw out if you're still having trouble past that or if that strategy is unpalatable to you. You could pick up a couple AWS certifications.
They aren't easy, but they aren't that hard either.
AWS Certified Solutions Architect - Associate
AWS Certified Developer
These certs are extremely similar and if you study for one you can do just a little more and pass the other too.
Cloud skills are in especially high demand and some companies agreements with AWS even require them to employ a minimum number of people with AWS certs.
The AWS certs in particular are nice because they are quite cheap compared to many certifications. $150 each for the 2 I mentioned. You'll want study materials as well. I really liked the courses offered by acloudguru which I believe is now owned by linux academy.

In any case sorry you're in that situation. Job change is always stressful, especially when it doesn't go smooth. Good luck!
