Play Store warning about deobfuscation

I got the following warning when uploaded by new release to the Play Store:

:warning: Warning
There is no deobfuscation file associated with this APK. If you use obfuscated code (R8/proguard), uploading a deobfuscation file will make crashes and ANRs easier to analyze and debug. Using R8/proguard can help reduce app size.

Any idea if I should be concerned about this, and if so, what to do about it?
Thanks.
