We are using web8.5 (none of DXA or DD4T) and consuming content delivery API in a web app with ActiveMQ\JMS cache enabled. We are hosting multiple sites in the same presentation server and one of the sites the dynamic content isn't getting updated on publishing. Only after an app pool recycle the changes are getting reflected. I have checked config values in the site's storage config and they are the same for all the sites and also I am confused about how to debug it as I don't see any error logs on the microservices side or presentation side.
I would appreciate any help on how to debug it.
