The latest version of our iOS app (2.5.1) introduced support for hardware video acceleration, which means drastically better performance and battery efficiency. Unfortunately, this version also introduced a bug which prevents the app from establishing a connection under certain circumstances, in particular when using Gruveo over 3G/4G.
We have fixed the bug and submitted version 2.5.2 of the app to App Store for review. Based on our past experience with the App Store review process, the update should become available within 1 to 3 days.
Thank you for using Gruveo and we are very sorry for any inconvenience this could have caused. Please feel free to contact us should you have any questions.
