Subtitles not appearing on iPad Pro (Version 1.9.7)

[Mike_Scott23 1]

I am experiencing the issue whereby subtitles do not appear when the video plays on my iPad Pro. The same video plays with subtitles perfectly on my Samsung Galaxy S10+ as well as my Windows laptop. Here are the following information if required:

1. Currently a premium member with Emby (Hardware Transcoding option activated)
2. Emby on iPad running version 1.9.7
3. Same video file plays fine and subtitles all display perfectly on Android phone and windows laptop.
4. Huge buffering when played on iPad Pro (Please refer to below screenshot). I had to drop the Quality to 480p - 1 Mbps to allow for smooth playback. Doubt that this is a Internet issue as windows and phone are running on same network and plays file fine in 720p
5. File Info:
