My feedback on the new PayPal module

[Juan GG Host]

1. The WHMCS documentation on this is very limiting and contradictory in places.
2. The documentation states it can still be used if you don;t have a PayPal account from one of the 33 countries listed, with limited functionality(i.e. no vaulting), but the linking process for this is unintuitive, and results in a bunch of errors when linking. Despite the errors, the module could be activated.
3. The documentation states the unbranded credit card sb-module can be used if not in one of the listed 33 countries, but without vaulting, however the siub-module cannot be activated if not in one of these countries (?)
4. There doesn't seem to be any way to modify the CSS of the payment window. This is a problem with the darker text in use, as it cannot be seen if you use a dark background for your cart. Workaround is to modify the cart page's CSS for that window.
5. There doesn't seem to be a way to modify the LANG variables used in the module. Changing the PayPal LANG variables in WHMCS's own language file has no impact. This is a problem, as our checkout button sits on the menu on the right under the order summary, but the PayPal module instructs users to "click below to continue". This confuses customers, who end up not checking out.
6. The new PayPal module initiates a payment hold prior to the checkout being completed. Customers reported getting payment confirmation from their banks when entering payment details, and thus do not complete the checkout process as they believe it is completed already. The transaction is then automatically reversed by PayPal a few hours later.

We've opted to remove this module and go back to using the older module. 

It's interesting that WHMCS do not use the new module on their own cart and invoices either. I can't help but wonder if it is due to the above issues.
