Thanks, @WLG3R! I would agree with this advice and wanted to confirm this approach. We launched the newest version of Drops on August 18 that will outlast V5.
As mentioned in that announcement, the past version of Drops will be available into January 2021. If your campaign ends before this time, feel free to use either version. If your campaign will extend beyond January 2021, you should use the newest version of Drops to avoid duplicate work or disruption during the campaign.
