Hi, @sologlory !
Katy here from Shopify. I hope you are well and thanks for reaching out.
That is a little strange. We have not had any other reports of this. Would you be able to share a screenshot of what you can see? For example, any error messages or flags?
Below are the requirements for the eBay sales channel. Could you ensure that you have not adjusted any of the following:
As this is a third party sales channel, usually the best point of contact would be the channel developer directly. If all of the above information is in order, and you are not seeing any errors, I do suggest to reach out to them here or here (depending on the exact service you are using).
I do hope that this helps, and that you have things up and running again soon.
Ah that is interesting, @sologlory. Great digging there, and thanks for sharing.
I suggest to touch base with the app developer regarding this, if you have not done so as of yet. Though I hope that working with a different browser helps in the mean time.
