You can never get a completely accurate approval ratings. However there is enough evidence that a nontrivial percentage of russians does not disprove of the war. Besides the ones already mentioned in this thread, don't forget that it is not Putin personally fighting in Ukraine or arresting protesters or posting propaganda. Does it matter if it is 70% or 40% when it is obviously enough for the state to continue its control over the populace and thus could also compel their IT companies to work for Kremlin needs and against their users.
