This has been driving me nuts all day. I package a game for Android and install it on my phones. Works perfectly. I make some changes to the level design to tweak my game and then package again with the exact same shipping settings as before but then I get the “No OBB file found”. I get the same message on all 3 of my test phones. I re-package the file 2 or 3 times without changing any settings at all and then it magically works again. Why? I made 0 changes but just packaged it over and over and then eventually it works. What is going on? I’ve tried this on 3 separate android phones with the same problem: a Xiaomi Redmi 8 Pro, a Sony Xperia XA2 Ultra and a Huawei P20 Pro. I really need to solve this because it’s driving me bananas having to wait for Unreal Engine to package the APK over and over. Sorry if I sound angry, but I would really appreciate some help on this issue.
