Disney+ (Disneyplus) stopped playing videos, workaround: Windows user agent

[kalpana]

I've been using Disney+ on Kubuntu 20.04/Firefox for a while without any special configuration (except for allowing playing DRM content in Firefox settings). Videos suddenly stopped playing at some point during the last few days. When clicking on the play icon, an icon might spin for a second and then nothing. Same issue on Kubuntu/Chromium and Fedora 36/Chrome.

The following issue is shown on the Chrome Developer tools Console output (and a similar one in Firefox):

vendor.fcc3d378e3f325b62130.js:2 Possible Unhandled Promise Rejection: TypeError: Cannot read properties of undefined (reading 'deviceProfile')

DeviceProfile sounds like they're trying to get some info from the client, so I tried switching the browser user agent to a WIndows one. That seems to fix the issue (on FIrefox install a user agent switcher add-on like "User-Agent Switcher and Manager", change the user agent to e.g. latest Firefox on Windows).

Just a FYI + is anyone else experiencing this?
