I have purchased EPCalSync so I can use it with my Kindle Scribe so am working in Universal Mode. However I cannot generate a calendar as I get the error shown. Please help!

This is one of the biggest updates we’ve released. We’ve introduced Universal Mode — which opens CalSync up beyond just reMarkable. 📥 Download Latest Version (1.1.0) Apple Silicon (M1 / M2 / M3) https://www.einkpads.io/api/calsync/darwin/arm64/releases/latest Intel Mac https://www.einkpads.io/api/calsync/darwin/x64/releases/latest Windows https://www.einkpads.io/api/calsync/win32/releases/latest What’s New — Universal Mode - Works with all popular tablets (including iPad) - No Developer Mode required - Generate your planners exactly the same way as before - Planners are transferred manually in this mode 💡 What this means Until now, CalSync was tightly integrated with reMarkable. With Universal Mode, you can now: - Use CalSync on devices like iPad - Generate planners anywhere - Stay in full control without needing special device access This makes CalSync more flexible, portable, and accessible. ⚖️ Important to understand - reMarkable Mode → Full automation (push directly to device) - Universal Mode → Manual transfer, but works everywhere - You now choose what fits your workflow. We’re opening the door wider with this release. More flexibility. More devices. Same powerful planner system. Let me know what device you’re using this on 👇

Like many others, I am sure, it's great to be able to test out Remarkable before committing to such a large purchase. Is there a way to trial EP CalSync to see if it helps make the case to keep it? Also do you need to permanently set the Remarkable in developer mode or is that just for install? Thanks.
