Absolutely correct.
I ran into the same problem, tryin' to move a downloaded file from the general download folder to the working folder of my app. Works with APK29, but not with APK30 thanks to newly introduced and very helpful "security restrictions". Another nice and absolutely useless ANDROID-addition. Unfortunally we have to live with it, finding again and again workarounds. GOOGLE makes the rules, but it is becoming more worse with every new rollout of a new ANDROID-version for developers.
