So, this confirms that you are missing your obb for this build. There are no expansion files listed.
Since you’ve already published this, I’m not sure that you can delete it and re-upload it. You’ll need to make a new Android build with the StoreVersion in AndroidRuntimeSettings set to 2 and upload both apk and obb to the store.
When you upload the apk, before clicking save or publish, above where you can type “What’s new in this version?” text, you should see an option to upload expansion files.
