I'm a professional resume writer and job search strategy consultant (20 years of tech recruiting experience), and I'd be open to taking a look to see what the issue might be (see my profile for contact info). It might not even be the resume, but instead your approach to how you're applying. If you're just sending resumes through Indeed and hoping for responses, you're doing it wrong.
The age thing may be an issue of course. If it's abundantly obvious from your resume that you are 60 or older, a reader may make assumptions about you that aren't true. Once a client reaches 40 I typically start to at least address the possibility of ageism and options to mitigate the risk if they are interested.
There are even some simple things such as resume formatting that could be at play. For examples, resumes with tables and images can be more difficult for ATS systems to parse.
Dozens of possibilities. I'm happy to take a look if you'd like.
