Steps to reproduce the problem:
1. Use an iPAD, and iOS last version, 10.2
2. Use Safari or Chrome browser
3. Play any Google Drive video. Before doing that, make sure to add a SRT subtitle to be embedded in it. Then, while using any iOS browser (for iPAD), try sending the video fullscreen, in order for you to see the subtitle languages available. Try selecting a subtitle from the list. Won't appear.

Video with subtitle embedded:
https://drive.google.com/file/d/0Bz47srLwNOKBX3h0YVQ5YURucVk/preview

Try playing that video using a PC. Then test it using the iPAD/iOS. As you can see, the video has a subtitle.

What is the expected behavior?
Where do I begin?

Guys, this is what is happening: Google changed GOOGLE DRIVE design for iOS, and this is what went wrong:

- While using iOS 10.2 and any browser, now we can't read subtitles added to Google Drive videos. I added a subtitle to this link, for example:

https://drive.google.com/file/d/0Bz47srLwNOKBX3h0YVQ5YURucVk/preview

A SRT file. While using the PC, I can switch between subtitle languages/files. I can switch betweeen resolutions. For example, 360p, 480p, 720p and 1080p. And I can read these subtitles just fine.

However after this change for iOS both of these things are gone. We can't read any subtitle and we can't switch between resolutions. Now the browsers for iOS are behaving exactly like the Google Drive app from Apple-Store.

So this is a regression, and yes, all of this worked before. The difference is that BEFORE we couldn't watch any Google Drive video (in iOS) in fullscreen. I remember to have opened a bug report months ago and the idea was being considered for further updates.

And I also remember that I managed to watch things in fullscreen in iOS by using an useragent to iPhone.

However, the player looked and worked exactly like iOS for iPAD is working now. Lacking these two crucial features.

The funny thing is that Youtube can also go fullscreen in iOS for iPAD (using a browser, not the official app), but in this case the subtitles are all displayed in a white font.

I suggest you use a PC and any iPAD browser, and try to reproduce this bug, acknowledging that subtitles are now gone from being read from any Google Video that exist.

What went wrong?
Read above.

Did this work before? Yes Don't know, but it worked fine in October, 2016
