Issues with Search Function for Existing Plans

Is anyone else having issues with finding/ locating existing plans since the Planner Update?  We are finding many inconsistencies with people in our organisation being able to see in the plan list, and/ or find existing plans in the search function.  For example, one worker cannot locate and existing plan but I can see the plan in my list or find in my search.  We are a small organisation and we share all plans with all workers so access/ permissions to the plans is not the issue.
