Some of you may experience this frustrating issue when trying to navigate your site's sub-sites: if you tap one of them, SharePlus will render the same parent site over and over again.
This is because of a bad AAM (Alternate Access Mapping) configuration.
When you tap a site, or sub-site, SharePlus uses web services to request to your SharePoint site a list of all sub-sites and lists. When your AAM settings are not properly set, your site "sends" SharePlus the same information about sub-sites and lists regardless the sub-site you tap. Because of this, SharePlus understands you are trying to navigate the parent site and so displays it.
For a tutorial video on how to configure AAM you may refer to this Microsoft article.
I hope this helps you. Best regards.
