Hi @fzanca ! Thanks for reaching out.
Instagram’s in-app browser can be quite limited and sometimes blocks certain scripts or media from loading properly — this behavior can vary depending on the device, OS, or even the video source.
We recommend testing the page in the native browser on the same device (e.g., Safari or Chrome) to see if it works as expected there.
For more personalized help, feel free to open a support ticket at https://prestoplayer.com/contact/ — we’ll be happy to dig into this further with you!
