Ah, I didn't know that. I am running the Electra jailbreak on an iPad Air 2 with iOS 11.2.6. Downloading the v2.7.4 activated link from Akila now.
EDIT 1: Okay, managed to install v2.7.4 via iFunbox but could either of you kindly post or PM me instructions on how to keep it activated and update it to 2.9.1 or v3 because at the moment, as soon as I open the app, it goes to the activation screen and asks for user details or demo mode. I remember getting around this back in iOS9 days but have forgotten since.
EDIT 2: Just experimenting with the app. After installing v2.7.4, I didn't open the app and continued to copy the baseline files over through iFunbox into 'var/mobile/Containers/Data/Application/AppGUID/'. This made sure that the app remained activated when I started it but now I get the following error: https://ibb.co/vd9zMNq
I've hit 'Resume' several times but it doesn't do anything.
I guess I missed an important step somewhere but I'm not sure what it is. Would gladly accept help from either of you.
