My retroarch experience is ruined, please help

I just bought a new iPad mini 2 Retina(7.0.6), downloaded retroarch with a few ROMs and everything was running fine. I never close the app, I just leave it running in the background, however, on more than one occasion the app has crashed when I’ve tried to re-enter it(by double pressing the home button and selecting retroarch from the screen of open apps). It feels like I have tried everything but once this initial crash occurs there is nothing I can do to get the app running again. I’ve tried fully closing the app, changing the date and re-initializing, crashes. Rebooted my iPad, changed date, crashes. Removed all roms/files, rebooted, changed date, crashes. The only solution is to delete the app and re-download but it takes days for me to do this because whenever I try to download the app from Emu4ios it tells me ‘retroarch could not be downloaded at this time’. It’s a complete nightmare. I just want to play some of my old favorite games and I cant. There has to be a solution, these issues have been driving me crazy for the past 2 weeks so if anyone has any info that can help me please reply! I’ve almost given up

My issues:

1 Crashes when I try to re-open from the background and then crashes everytime after that on start-up so the app has to be deleted and reinstalled.

2 Can’t download retroarch through Emu4ios(gets it from github), get pop up ‘retroarch cannot be downloaded at this time’

If you’ are on 7.0.6 jailbreak it, so you can install official builds… And by the way, you’ll never get support from here because you are using pirate builds. See you!
