Hello everyone - my name is Paul McMahon and I am one the lead architects for AEM at Accenture (I started my AEM career at Acquity Group), My love for the product goes back to my first implementation in 2002 on CQ 3.2 (before the days of the parsys or CRX :-)). The growth of community over the years...

My thoughts below:Internationalization - the tool will support as many languages as you want. If you talking about adding additional language for sites you manage in the tool see the translation and multi-site manager sections of the documentation (https://docs.adobe.com/docs/en/aem/6-2/administer/s...

Have you checked the logs around the time the workflow kicked off for error messages that might indicate a problem in the proces...

50 concurrent users is close to the top end of the performance profile for a single authoring instance. Which version of the software are you on? What sort of hardware are you running on - what number of CPUs and how much memory? How is your storage connected - do you have a fully optimized IO solut...

Have you looked not just at the bundles but also the services? Check the following:Is bundle A activeGo to services console - check to see if Service A is active and runningGo to the services console - check to see if Service B is active? If it isn't why - are there unfilled dependencies? Try to act...

I am not sure I fully understand you use case, but it sounds to my like what you are describing is something that falls under the Multi-Site Manager functionality. In you use case you have the same page in two locations, and one is the master and the other is a copy of the master and  you want to be...
