The above issue could be related to the fact we were running Tapatalk Version 4.2.0 (which was released in October 2014) and there had been three new versions since. I have therefore outlined the changes (some of which may not affect normal users) below:

Version 4.3.0

• Added function to activate forum accounts via SSO
  
• New and improved Smart Banner design
  
• Admin CP SSO Settings merged. (Combined "Native Registration and Social Sign On (Recommended)" and "Native Registration Only" sections to single "In-App Registration" section)
  
• Added function to auto set forum api key
  
• Optimized push code
  
• Other minor bug fixes
  

Version 4.3.1

• Fix a smart-banner display issue
  
• Fixed an XSS issue on the welcome screen
  

Version 4.3.2

• Optimized smartbanner code
  

This does not serve as a guarantee that the issues will be resolved, but here's hoping, eh? Even if it doesn't resolve our issues, at least we're up to date on the updates front again!
