I have an app named "Lightning Knowledge" that is using the Console Naviation. Yet, I am still getting the following error:

Challenge Not yet complete... here's what's wrong: 
The Lightning Knowledge app doesn't have the ability to view either or both: recently-visited primary tabs or subtabs.

I have tried deleting it and recreating it. Even tried creating a new org. Cannot get past this challenge. 

Any thing I could be missing?

Error Message:
Challenge Not yet complete... here's what's wrong: 
The AccountTab Visualforce page does not include one or both of the following: the apex:slds tag in the page, or the slds-table value in the table.

Hello all. I am working on the new superbadge and getting stuck on Challenge 3 . I have tried several solutions but cannot get the data to display in table format. Here is my code below, my main issue is where to place the table class in realtion to the pageBlockTable.

<apex:page standardStylesheets="false" standardController="Account" recordSetVar="accounts" tabStyle="account" applyBodyTag="false">
    <apex:slds >
        
        <div class="slds-scope">
             
                <apex:pageBlock>
                    
                    <table class="slds-table"> 
                    <apex:pageBlockTable  value="{!accounts}" var="a">
                       
                        <apex:column headerValue="{!$ObjectType.Account.Fields.Name.Label}">
                            <apex:outputLink value="{!URLFOR($Action.Account.View, a.id)}">{!a.name}</apex:outputLink>
                        </apex:column>
                        
                    </apex:pageBlockTable> 
                    </table>
                    
                </apex:pageBlock>
            
        </div>
    </apex:slds>    
</apex:page>
