We use module M2OSC v2.2.3 on M2.2.6 and found that it stuck on the one-step checkout page.
And I try it on both Chrome and Safari, even in private mode. But still get the same result. Please help.
The root of the issue is that the module is not compatible with PayPal on Magento 2.2.x at this time.
To solve this issue, we have removed this code
in file /app/code/Bss/OneStepCheckout/view/frontend/requirejs-config.js
Please check and follow the guide.
If you have any issues, please don't hesitate to contact us.
We'd like to help.
