After reading posts on cssu thread since release of v16/16.5 cssu and like others reporting problems with fastsms closing on pressing options box , i wondered if anyone has any ideas or thoughts as to whether fastsms fixable ? and if its definately a fastsms bug on all devices on v16.5 or if its only on some(not all) devices ?

fastsms is for me an essential app and this problem is concerning that i could lose it if i keep v16.5, i know it was ok on v15 so really hope that it can work again
