After much digging around, due to the incomplete and unclear instructions, I signed up for the Premium 14 day trial. After doing so and finding I still didn’t have access to any of the Free w/Premium designs, I received an email that read, in part:
"For the next 14 days, you can explore all of the new Premium features in your Glowforge app for FREE, no strings attached!
[Complete your upgrade] to unlock unlimited access to scores of designs that print at the click of a button, and get this month’s featured Design of the Month to keep forever. If you upgrade now, you won’t be charged until the end of your trial."
Upon completing the upgrade process my credit card was immediately charged for a full month ($63.93 CDN).
Please reverse the charge, and kindly fix both your instructions and process.
