spathak pointed out the following issues in the Applications docs:

The majority of docs contents work as expected but some changes need to be done in both ROSA and OSD docs:

• In Viewing the topology of your application under the Display Options remove Mode (Connectivity or Consumption) as they are not present in UI anymore

• In Creating a rolling deployment under Procedure after the first step oc new-app quay.io/openshifttest/deployment-example:latest this can be included which is also suggested by the result of step1:
  The image does not expose any ports - if you want to load balance or send traffic to this component
  you will need to create a service with 'oc expose dc/deployment-example --port=[port]' later
  then we can go for step two as mine worked after I created the service using the aforementioned command

• There is just a slight mismatch in output in Step1. I don't know if it can qualify for correction -
  The example output for oc get quota -n demoproject is partial, it should have all the quota requests and limits against the quota name:
