My gif, created with Animate stops looping only on a PC

Hi,

My gif, which I created with Animate stops looping only on a PC. I started a little download shop for gifs, but when I download them on my Ipad or my Iphone the animation doesn't stop.

I was used to Flash/ SWF and I have to relearn a bit Animate. What I did, I created a small animation with Animate, then went on export/animated gif/ then put the loop on one time NOT endless.

It works when I import the gif into my website or a testwebsite, or when I watch it in my photodatabase on my PC - there it plays only once like desired, but on an Ipad Pro or Iphone it turns endlessly.

Thank you so much in advance for your help!
