SAP Fiori Approve Request - Bad Performance & Http status 404

Hi ,

we have set up 2 Fiori apps based on the general  "SAP Fiori Approve Request" serving the Purching PR Approval  and the HR Leave request services  because the dedicated FIORI PR Release & FIORI Leave request apps where not suitable for our customer case.

In both cases we  face 2 problems

1. we have to wait for a long time for the app to fetch the initial data when we try that using a laptop

2. we get the error Http status 404 when we try them using a mobile

Any suggestions for speeding up the initial collection and for troubleshooting the http error ?

Thanks
