Sharepoint iOS App is not showing my entire list

Hello,

I have a strange issue that just surfaced. I have a small list in SharePoint Online with 182 items. On a desktop browser, I see the entire list. However, when viewing the list through the iOS SharePoint App, I only see 105 items (Sorted by Default,  and no Filters). Also, applying filters is no longer working. I have cleared the account settings and reinstalled the app without any success. Any ideas what could be wrong? (iOS Version 12.01 - iPhone 6s). - Your help would be appreciated.
