Streaming issues on Safari/iPhone

[GreekGod22]

I am listening to OGSF through a monthly subscription. I am playing it from my iphone 12's Safari browser. I select 4 loops of Ultrasonic, and press play. The problem is that it won't play the full 4 loops. When the first loop is over, the loop counter/ time remaining is reduced by 1 loop.
When the 1st loop is over, time remaining should be 3h(2h59m), instead it is 2h(1h59m).

Ok, this is a bit frustrating, as I can't trust the web audio player to play the selected number of loops. Hence, I can't play it overnight. I had to select 7 loops for it to play 4-5 loops of OGSF.
Surely I'm not the only one with this problem. This makes the online subscription no longer a good option.
