paypal integration shopify

[Mrk5]

hello,
I would like to say that I have already opened a ticket at paypal-support.com, but due to the time difference the slowness of the file makes me worried and I would like to see if you can help me here in the commnunity.

I have a correctly configured business account that has been working for years, already connected to 2 shopify stores, 1 of which has been working for 3 years.

Now trying to connect a third shopify store I get an error message immediately after logging in, I attach screen.

If I try to connect another shopify account to the same store it works.

I have of course already tried changing pc, browser, incognito mode, clearing cache and cookies but I always get the same error.

Good day @Mrk5,

Thank you for posting to the PayPal community.

Please cross check your PayPal Business account and make sure it is verified and confirmed without any account limitations. 

Merchants can manually grant permission to a third party eCommerce to access specific information in your PayPal account and perform PayPal API operations on your behalf.

Login PayPal.com >> Hover on your name at the top right corner >> Account Settings >> Website payments >> API Access >> Pre-built payment solution >> Grant API permission >> contact your "Third party software eCommerce" for Third Party Permission Username >> enter the username.

If your still facing the issue, please create a MTS ticket via - https://www.paypal-support.com/s/?language=en_US with detailed error information. 

Sincerely,

Chiranjeevi

permission is already granted and in fact the account has already been connected to 2 other shopify stores for quite some time.
The "new" connections no longer work.
I can no longer connect it to any new shopify.

I have already opened the ticket but due to the time difference I get a reply every 24 hours and so far the help has been useless:
delete cookies, cache, disable 2-factor authentication, and meanwhile it's 1 week that I can't open the store and accept sales.

I also wrote several times the debug id I incur:
PayPal-Debug-Id: f538237cb5a73

PayPal-Debug-Id: f262045560d2f

PayPal-Debug-Id: f443410c3f9c8

I can't even try to delete the current API credential and recreate it, because if by chance the stores that have already been active for years stop working, that's big trouble, thousands of sales.
That's not a risk I can take

I solved it independently by opening the url https://www.paypal.com/bizsignup/#/grantPermissions immediately after receiving the redirect to the error page.
By manually pasting the correct url the integration worked.
