I believe that all the versions of rodinal are the same, be it adona or ro9, still made by Agfa and sold to the other companies in bulk and they re sell it under their own brand name.

Not quite. It can be very confusing.
WWII split Germany and the Original Agfa plants were around Wolfen Germany. The WWII formual was made and sold in the Soviet satellite area, often as R09. The East german Chemical plant is alive as Calbe.
Agfa reopened in the west and changed the formula slightly over the years. They sold there Consumer photo business to a Start up called "Agfa-Photo" including the rights to make and sell the "western" Rodinal. Agfa Photo reorgainized and much of the business was worth more for the real-estate than the photo business. In the process we lost APX series films. and the chemicals were sold to an outfit called A&O imaging, who was more interested in the Mini-lab part of the business.
The factory which made (Makes) rodinal is now owned by a contract Chmical maker. They will make almost any chemical you want. They don't have the right to call the Rodinal they make Rodinal or use the agfa or Agfa Photo name.
SO whoever orders a batch has to provide a name. Confusingly some use the R09 Name. Some also sell the east version as "original Rodinol Formula" (true since it is the older version from before WWII)
I think here in Canada the official name is Blazinal I am not sure as I am still using some A&O bottles, as I only use Rodinal for some films.
The way that may help is that the eastern stuff often was mixed 1 to 40 with Water, while the western stuff is generaly mixed 1 to 50. if the product you are looking at mentions 1+40 it is probably the eastern product. Calbe is in the unified germany so it also can say "Made in germany" and I think that Foma may make the R09 version as well.
Looking at Freestyles page the
The adolux APH 09 seems to be the eastern (since 1918) version.
Compard R09 one shot is Claiming to be the western version ! ("This is not an imitation or previous/older Rodinal formulation.")
The Fomadon R09 is probaly the eastern version .
