Thanks for your quick replys. Highly appreciate it 🙂
Maybe I will come back here and get in touch with you, but for now, I solved the problem using this site: https://ezgif.com/optimize
Here I get the option to remove frames, change the timing and compress the hell out of it. I had to try and error a lot but in the end I got it under 300kb.
Cheers,
Felix
