We have implemented DXA hotfix 2.0.1 with .net and Web 8.5 recently and also enabled ActiveMQ with it, by following steps mentioned here
Mostly, it's going fine and the cache gets invalidated for most of the changes like page, component etc. The only area where it is not working is when we access dynamic components.
Even if we reduce the cache duration to 5min, the only way to clear the cache is to restart the content service. We have checked the questions present in stack exchange like this but we still have the same issue.
Any help would be appreciated.
