Hi my device is iphone 7 plus ios version is 14.2 I purchased the app 10 Nov 2019 it was working fine , two days ago it crashed as usual . I uninstalled it and then I tried to install it . The problem is when it installed it stays gray and i cannot open the iosgods App! When I tried to go setting to vertifed it gives me the option to install it over and over again ! when i click on the gray iosgods App It gives this msg: ( unable to install (( iosgods App+)) this app cant be installed because its integrity could not be verified). i tried to change the region , clear data, use vpn , switch internet data to wifi , restart my device, but unfortunately nothing work ☹️! i need help plz
