URL Management Youtube video issue
Looks like YouTube server issue (no such issue on the old course's platform odoo.thinkfic.com). The video works fine on all resolutions until 0:56. After this point only two resolutions are workable: 1080p and 360p. The rest are infinite loading. For 720p smartphones this is a critical issue: YouTube doesn't give you to select 1080p, and 360p is unreadable for smaller text, like URL text.
The same results for 3 devices: Android 5, Android 6 and Windows 7. Different network providers (mobile data, landline). Bulgaria 12-JUL-2019 10:00 (Sofia time)
