I've been fighting this for days now and found something that seemed to work... (apologies for the verbose mode but it may provide a necessary clue).
EDIT: Found the problem or at least a workaround... Scroll down to the Workaround section (lower below) to get to that bit if you want to avoid the verbose mode 🙂
Edit #2: Steps 1-8 didn't make a blind bit of difference (I think) as the window seems to be more critical... I've included it for completeness, just in case..
- Went into Paypal and checked my account setting for the Nth time.
- Spotted that under "My money" > "Your preferred way to pay" nothing was set (and figured what the heck, I've tried everything else!).
- Set the "Online purchases" to "PayPal Balance"
- Went back to my eBay checkout and clicked the "Paypal" payment option (for the 4 millionth time!)
- For some reason the normal pop-over window opened as a new tab/window instead of it's usual pop-over
- Put in login details as normal and for first time in forever got the 2F Auth prompt for SMS
- Clicked the send SMS button and then keyed in the code received
- Voila! I was logged in and the browser bounced around a little while it took me back to the checkout with "Paypal" finally selected
A key part of me wonders if the true issue was the pop-over window rather than the changed setting so I cleared the checkout, went back through the whole process again and as anticipated it borked out.
The Problem:
Something is blocking the script from writing back to the same pop-up/over window that you login to Paypal in. It's almost as if the script closes the window early (when you complete the initial user/pass login) and then tries to respond to the window it just closed, slams into a virtual wall and slides "gracefully" to the ground before ignoring the whole thing.
The Workaround/(Fix-ish):
- Go the eBay checkout as normal and get to the "Pay with..." option
- Select "Paypal" (no idea if this works with Paypal Credit btw).
- Wait for the pop-up/over window to appear.
- Look for the address bar at the top of the window starting "https://www.paypal.com/webapps/...."
- Right click on it (it "should" select the whole address but if it doesn't, right click it and then click "Select All")
- Choose "Copy"
- Open a new tab/window in your browser and paste the copied address to the address bar then hit enter/return/go
- You should now see a login form as normal
- Proceed as normal and hopefully you should find that the login completes its initial login along with any 2 factor authentication.
- It should then take you back to your checkout page where normal service with Paypal should resume with the option selected and "Confirm and pay" ready to go.
Further Info:
This method worked on the following system setup:
- Windows 10 64 bit
- Chrome browser span>
- Malwarebytes installed
- Paypal business account
