Hi Tammy,
Thank you for the reply - I read the second thread before I posted my question but it seems related to Lumira Desktop(correct me if I am wrong) and I have problems once I publish on the server before that it works ok. I also checked the memory setting on the server side and the logs for errors but I could not see an issue.
The other thread is related to SAP UI5 development but I am not using custom components - I just created a standard story in lumira desktop and published it.
Best regards,
Nikolay
