We are facing an issue on AEM 6.5.15 we use the "Production pipeline" on Cloud Manager to build and deploy on STAGE (1 author, 6 publish), and packages are uploaded but not installed on Author and Publish. We have the message "A different version is installed" that references the version before the deployment.
other details:
1. I verified the filter.xml files (just in case)
2. No snapshot as it is being versioned by the cloud manager (the version got stuck and not being updated too, that's the issue I believe)
3. works fine on Dev and QA
4. verified the code being updated on Adobe repo (so no issue with our Jenkin jobs)
