Akira Toriyama is heavily involved in writing the story of Dragon Ball Super. He does not write the script or draw the manga, but he writes the overall scenario and develops the basic story he wants to advance in his own way. The anime is more directly connected to his work, while the manga is more of a method of advertising the series. The manga is written by Toyotarō, who previously worked on a fan manga “Dragon Ball AF” under the name Toyble. Toyotarō was chosen by JUMP for his incredible ability to more or less emulate Toriyama’s drawing style perfectly. This has created confusion among fans, who might think Toriyama himself draws the manga. This is not true. The manga already has evident differences from the anime, which Toriyama is directly involved in. Toyotarō has the power to manipulate and adapt Toriyama’s basic story just as the anime staff can do, so this creates discrepancies between the two mediums. In the end, the DBS manga cannot be considered in the same light as the original DB manga was. It is used solely to advertise the anime, however, that does not mean in cannot be considered a part of the official canon of Dragon Ball Super and the series at large.
In short, once again the question of “canon” is up in the air. In this case, there may not be an official “canon” when comparing both the anime and the manga. Both stories were given an original draft by Toriyama, but both Toei and Toyotarō adapted the story in their own way.
