While running some test I noticed in the log that Applanga initial setup is taking more than 10 seconds so the OS is killing the app, only with bad network condition, if I run the same test without internet it's loading without issues so maybe you need to add a timeout
Conditions
iOS : 12.4
iPhone: 6, 7
Very Bad Network simulated with Network Link Conditioner
