Anyone who has installed the 1.2.0 release can correct those issues by copying the following into the admin's Tools :: Install SQL Patches
Code:
UPDATE configuration SET configuration_value = '1.1.0' WHERE configuration_key = 'MODULE_PAYMENT_PAYPALR_VERSION' LIMIT 1;
Once that's been run, navigate back to the Modules :: Payment page and the PayPal/RESTful module will update (properly) to v1.2.1.
I can confirm that works for sure upon testing. Many thanks!
