I created a new playground, selected it from the "Launch your Hands On Org" dropdown and tried to install the unmanaged package for the challenge - it only installs to my original DE. I've tried the incognito directions, I've disconnected my original DE org and I've tried to do the challenge in my original DE org but the package doe not install properly.  How do I install to the new play ground into the new playground.

There is a custom object Done, and I need to create a look up to account. When lead is converted I need a record in done object which is related to the account. Please help me with this. Suggest me in Process builder

Lead Status
If Lead Status is Active or Follow up, I wanted to follow up with lead in 10 days or older and it should automatically redirect to Campaign (Custom Campaigns) and show us the report of it and then we can follow up with lead through dialer. So below screenshot shows the dependant fields, and there we have Lead Status. So how will it redirect to the Campaign if Lead Status is follow up with 10 days or older? Pardon me if I did any wrong in question

Last note and notes should get auto populate if we fill one in either of them.
I had custom field LAST NOTE in my opportunity layout. And I had field New Note is under Notes and Attachments related list in the layout. When we enter the Last Note, I wanted to display the same in the New note? How does it possible? I mean without doing it twice (Copy and paste), I just wanted to auto populate it.  when I create Last Note, it should get auto populate the same in New NOTE and create record whenever I create Last note which means there should be all the information in Nee Notes related list whenever I create last note.
Can you please help me out.Thank you
