I got your point but the issue is that your server already caches the info so that it may happen:
I also forwarded to our developer for further update to avoid cache from our extension but again, when there is cache on your server, you need to clear it first to see the new changes.
If you have access to your server or contact your hosting provider for help to not cache the JSON file.
I hope this makes senses.
Now we are talking
So
1. I will contact the host and see what will happen with JSON you mention
2. The only way to refresh the prices (without OF COURSE asking the visitor to clear THEIR browser's cache!!!!) is to move "price" filter from Front-end Display Elements to Unused Content Elements and Save AND THEN move "price" filter from Unused Content Elements to Front-end Display Elements and Save. This of course is impractical to take place every time we change prices.
deftosxromata You can try to disable cache first and see how it goes.
I asked host and they disabled php cache.
Problem fixed. FINALLY...
deftosxromata Glad to hear that 
Well the problem resurfaced. I now sent email to host to ask if still the php cache is disabled.
Have you sorted out this problem in any later versions of JA Megafilter?
Hi deftosxromata
For the last some months, our team focused more on updating products for Joomla 4.
I checked with the dev team, and since it is about the cache, we could not resolve it in our product. I hope you understand and help get the issue resolved with your hosting provider.
In case we find any better solution, we will update you.
Have a nice day.
Best regards.
