Cannot load my model driven app anymore and very slow speed overall...

While fighting a deadline, now my Model Driven app refuses to load, display data from the entities page is mega slow now...

I just found this issue in the O365 Admin... It might be related, but doesn't' specifically mention model driven apps not loading 😞

Since I'm not using the marketing components, can anyone confirm the issue below also does impact Power Apps and CDS 2.


  • CR139439 - General performance degradation
  • Status: Service degradation User impact: Users may experience slow load times and failed actions when using Marketing for Dynamics 365. Latest message: Title: General performance degradation User Impact: Users may experience slow load times and failed actions when using Marketing for Dynamics 365. More Info: Users may receive slow load times that lead to timeout errors. In addition, users may also receive the following errors when performing tasks that utilize customer data, such as creating customer journeys, "Failed to go live because an error occurred.” Or, "We couldn't check the page for errors at this time. Please try again later.” Current Status: Following a series of node restarts, we have identified additional nodes impacted by the high memory utilization. As such, we will perform node re-balancing to spread the impacted request workload evenly across our infrastructure.

Hi @VFXPro1 - I'm not aware of any outages on Monday that would have impacted this, but we can check your specific environment. Can you confirm if you're still seeing issues?


If you can please raise a ticket here : with your environment details and the time the issue occured, we can have one of our team investigate.


I have been plagued with this over the last week as well.


Extremely slow load times in the model driven apps themselves, chrome dev console reporting a large number of performance warnings:

Performance issue (type: warning): Work block action(s) timeout | Work timed out with no activity.


My .net clients that use the xrm tooling sdk are almost non functional because of timeouts (currently set at 2 minutes).




@VFXPro1 and @jdvachal - I'm sorry to hear you've been having problems - can you both please raise a ticket at so your specific environment can be investigated - the support process will gather some information from you so our team can look further into your environments.


I have ticket 10327489 open to track this issue.
