the issue

The polyfill function for Promise.allSettled is not being served for a few User Agents (Opera Android, in most cases).

example

• Polyfill.io URL: https://polyfill.io/v3/polyfill.js?features=Promise.allSettled
• User Agent: Opera Mobile 45.1.2246 - Mozilla/5.0 (Linux; Android 6.0.1; SM-N910F Build/MMB29M) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.141 Mobile Safari/537.36 OPR/45.1.2246.125351

according to the specs, the function is only available from the version 54.

This was addressed in v4 of polyfill-library, but this service still uses v3.
