Redirects Not Clearing

(Digital Ocean + Cloudflare setup)

I added some redirects with the redirects.json file. Worked great. I didn’t need them anymore, so I updated the redirects file with a clean version.

I restarted ghost server, clear cache from server, cleared cache from Cloudflare. However, people have the redirect cache stuck locally in their browser.

If someone is new to the page, they get the updated correct links - without redirects.
If someone with browser cache visits the page, they get redirected with the old redirects.

Is there any way to fix this or do I have to ask everyone to clear their browser cache?
