Load custom firmware to module using playground

Is it possible to load custom firmware to a module in playground in stead of using Toolchain?

When I upload a custom firmware in Playground the Firmware and Version info are not loaded and the Flash Firmware button does not become active:

I ask this because I want others to be able to update their device remotely without having to install and understand Toolchain.

I’ve tested that now and I can confirm that it is a bug. I’ll report it. It affects v1.2.0 - tested on Windows 10 & Ubuntu 18.04

I’ve tested and used Playground v1.1.0 for long time and it is working perfectly there. Can you use this older version?

Thanks for testing, v1.1.0 is a good workaround for now.
