Where can the latest firmaware version numbers be found for the Spark.
AC firmware version
RC firmware version
Battery firmware version
DJI GO 4 (iOS version)
DJI Assistant 2 version.

I have asked this before and was provided a link to that information. Now that link only accesses the Spark technical specs.

Please provide a new link to this version information.

Well, I guess I should not feel too bad about not finding where DJI has hidden this apparently proprietary information.
Even the Admins (DJI Stephen) find it beyond their authority to disclose this information.
Pitiful!
