Deprecation in Dynamics 365 in 2020
Summary
The functionality to make the Unified Interface the only client available is available now but the default is to keep the default app / web client available, but this can be changed in the system settings by clicking “show legacy Dynamics 365 – custom app” equals Yes. This will make sure that all users start to transfer to the Unified Interface as the web client will not be available if the above option is set to No. See the link to the Microsoft page about the rules to explain which feature of PowerApps has been deprecated. This is as there were a few problems with these attributes as they didn’t fully show the correct stage that the business process flow was on. See link to the Microsoft page about enhanced service level agreements and how they work.
