Is there a real contradiction between AN 3.47 and SN 15.9?

The setup ...

Mendicants, conditioned phenomena have these three characteristics. What three? Arising is evident, vanishing is evident, and change while persisting is evident. These are the three characteristics of conditioned phenomena. AN 3.47

Together with ...

Why is that? Transmigration has no known beginning. No first point is found of sentient beings roaming and transmigrating, shrouded by ignorance and fettered by craving. For such a long time you have undergone suffering, agony, and disaster, swelling the cemeteries. This is quite enough for you to become disillusioned, dispassionate, and freed regarding all conditions. SN 15.1

Along with the assumption that "transmigration" or "samsara" is a conditioned phenomena ... Would seem to give rise to a contradiction. On the one hand, the Buddha said quite unambiguously that conditioned phenomena have a beginning, middle and an end, but on the other hand the Buddha said that "transmigration" or "samsara" has no known beginning. Questions:

1. Do you agree this is an apparent contradiction?
2. Do you think this is a real contradiction?
3. If it is apparent but not real, then how would you resolve it?

I would say, "yes, no, and it is complicated" but I'm curious to know how others resolve it. Related but distinct questions. UPDATE: This was too close to a seeded question. Although it was asked sincerely in that I was curious to know others responses (particular users on this site who I respect and admire) I do have my own idea of how I would answer this question so I should not have opened it out of mere curiosity. I was going to delete it given it goes against the site moderation guidelines, but then there are good answers and we are discouraged to delete questions where people have attempted to give good and thoughtful answers so I will leave it, but I do regret opening it in the first place.
