Paypal JS SDK not loading for some users

[freddyhaddad]

Library used

direct script integration, as follows: https://www.paypal.com/sdk/js?client-id=[OUR-CLIENT-ID]&components=messages,buttons

🐞 Describe the Bug

We set up sentry to report when an external <script> tag failed to load (triggers an onerror event).
For 1% of our users, the SDK script tag is unable to load. It works for 99% of the users since we still get payments, but cannot reproduce locally.
Watching some affected user sessions show the user being frustrated as he cannot find the Paypal Smart Buttons on the page.
Moreover, window.paypal is not available right under the asynchronous script tag for these users.

All browsers are affected, desktop and mobile, Chrome/Safari/Edge

We use the Paypal JS SDK on 3 separate websites, and the issue happens on the 3 sites.

🔬 Minimal Reproduction

Cannot reproduce

😕 Actual Behavior

The direct Paypal SDK JS script tag triggers an "onerror" event, and window.paypal isn't available which triggers subsequent errors upon usage.

🤔 Expected Behavior

Expected Paypal JS SDK to be downloadable by all users' browsers.
