FORScan Lite v1.5.9 for i.o.s?

[JohnKarpenter]

Has anybody experienced issues with v1.5.9 on iOS devices.
Lite version worked fine on iPad and iPhone with v1.5.8 but since app upgrade it will not detect the elm. FORScan viewer works fine. I have cleared cache deleted and reinstalled but always same result. ELM is ok as works with viewer and connects to FORScan on PC by Wi-fi without any problems. I have loaded an old iPhone with v1.5.8 as to old to accept latest and it’s absolutely perfect. Would just like to be able to use my main phone as hassle with PC or carrying additional phone around. Any ideas or a way to revert back to v1.5.8.
