Playback error on Samsung device android 15, Mobile plan.

Immediately after restarting my subscription and paying for my showmax mobile subscription I was met with a playback error. I contacted showmax support team and they escalated the matter but a week later they tell me that the issue is that my device, a samsung AO5 has android 15 and there is a known issue of Samsungs and android 15. After they said that they said that I should use an alternative device, which alternative device, I only have 1 phone so must I borrow someone's phone just to use it. This is unacceptable and I asked if I could get a refund or if they can upgrade my subscription to include a laptop so I can use it as an alternative device and they refused. This is unacceptable because if the app doesn't then you are on your own as if you didn't pay for the subscription. I also have netflix but never had any problems because im using a samsung device or android 15. If you have a Samsung and its using android 15 dont do it because if it doesn't work for the same reason as mine then you are on your own.
