In my attempts to understand the Licensing API despite the lacking documentation I’ve attempted to install trials of no more than three different plugins. All resulted in failure. The Extension Manager says licenses where missing for all of them despite the Warehouse saying they all had several days of trial and had a link to install the trial.
The extensions I’ve tested are Cadman Report Tool, su4u-Components and s4u-Slice. The s4u extensions exposes the return value of ExtensionLicense#error_description tobthe user, which in both cases was “No license for product (-1)”
Has anyone else had any luck recently with trials from Extension Warehouse?
