With the new render engine (Build: 7.1.0.2052) when any entity is opened we can see the loading circle and instead of "Requesting Data from CRM" we receive in German Language "Fehler beim Anfordern von Daten vom CRM" which means in English "Error requesting the Data from CRM"
This is very confusing for the users and is causing incident requests.

We have reproduced this bug in a vanilla CRM Online Deployment!
