Hi everyone, I have an iPad Air 1, with each software update it’s been getting slower and slower as you would expect but still performed well enough. Since updating to ios 11.3 however apps keep crashing-specifically local apps. I live in South Korea and most of the South Korean apps I use won’t even open (they have been perfectly fine in previous ios versions). The apps have all been updated to the latest version but when I try to open them they pause for ages then the screen returns to the home screen. Has anyone experienced something like this? Is there something I need to do in settings? I have done a hard reset, tried reinstalling the apps but haven’t resorted to a full restore yet. Wonder if it is an app problem and should wait for another app update or is it something in ios? Thanks in advance for any suggestions.
