Enforce Field Formats for Sugar

Hi, We're in the process of upgrading our on-prem SugarCRM instance from 11.0.3 to 12.0.3 and recently purchase the SynoFieldMask addon subscription for SugarCRM 7.x to 13. We've successfully installed SynoFieldMask for SugarCRM through the Module Loader, after SugarCRM was upgraded to 12.0.3, but we're unable to successfully validate the license. We had experienced this issue during the trial version and continue to have issues after purchasing the yearly subscription. Steps to reproduce: 1. Navigate to Admin (Administration) using a SugarCRM Admin account. 2. Navigate to the SYNOLIA subpanel > License Keys 3. Enter the Field Mask License Key (copied and pasted from SugarOutfitters > Account > Purchases) and click Save 4a. Popup prompt states: Error: License validation valid* 4b. License Status value is: License is Not Valid * There is a 500 status error when attempting to access https://_domain_/rest/v11_16/SYNO_Settings/config Please let me know if you have any questions or need more details. Thank you.
