iOS app says "Server is Outdated" despite being current

I don’t have a WD MyCloud Home to verify.
Here’s a post describing how the update should work

How do I Update My Plex Media Server? Currently on Version Version 1.32.5.7358

Go to the MyCloud administration web page for the NAS. Go to the Apps page. Under Installed Apps, go to Plex and turn it off. [Plex Upgrade 1] Then click on “Install an app manually” and select the file you downloaded. [Plex Upgrade 2] Answer that you do wish to reinstall the app, when asked. The update will then install and then restart when complete. Easy peasy. Have fun!
