Personally I never had this issue with UE 4.25.4. But we had to update to 4.26 for Android because they fixed some exposure issues which we’ve experienced with 4.25.
But since we are not able to build for older Apple devices with 4.26 anymore we now need to have two separate branches one with 4.25 and one with 4.26. So the problem is “kind of” solved on our end for the moment.
