Vimeo videos usually do not play at all in Brave desktop for Ubuntu, nor in Brave for iOS

Description of the issue:
When viewing videos posted via Vimeo player (in any websites found so far), in both Brave for Linux (Ubuntu 14.04LTS) and in Apple iOS (iPad Pro, os ver 14.x), the video landing image will be displayed, the player and controls are visible. On first click of “Play”, the player reacts as if loading the video, but then reverts to the initial screen. Subsequent clicks of “Play” produce no reactions. The video will not play.

On some occasions, a page refresh may allow the video to play, although other videos on the page (with multiple videos) will not. Does not appear to be affected by “Brave Shields”, at least, turning on and off does not change responses.

Steps to Reproduce (add as many as necessary): 1. 2. 3.
Open a page containing a Vimeo-feed video.
Click “Play”
The video will usually not play.

Example page (may be temporary): https://mypatriotsnetwork.com/patriot/maricopa-county-in-az-is-one-step-closer-to-election-justice/?utm_content=12324781&utm_medium=Email&utm_name=Id&utm_source=Actionetics&utm_term=Email

Actual Result (gifs and screenshots are welcome!):
The video will not play

Expected result:
The video should play. In all cases tested, the same page plays correctly in Firefox or Google Chrome on the same OS (Ubuntu 14.04), or Safari (iOS 14.4)

Reproduces how often:
Except for the one occasional refresh anomaly mentioned above, if the video does not play (the usual case), no amount of clicking or waiting will play the video. In most cases, even a refresh will not cause the video to play.

Operating System and Brave Version(See the About Brave page in the main menu):
Ubuntu 14.04 w/Brave Version 1.18.78 Chromium: 87.0.4280.141 (Official Build) (64-bit)

also
iOS 14.4 (iPad Pro 11", 2020), Brave Version 1.23 (21.2.12.22) exhibits the same problem, but never has been observed to play, even with refresh.
[page works for Safari (version not known)]

Additional Information:

@Mikesmith You can try disabling the shields and ad blocker on the pages. Hope it helps :slight_smile:
