Wrong firmware displayed in Web IDE

I’m unable to send OTA firmware updates to my Electron, as the target firmware is erroneously showing 0.5.2, when the device is actually updated to 0.6.0.

Looks as if this is a known issue, however, I was unable to find a proper workaround. Using a separate browser (caching issue?) didn’t seem to help.

Any way to force the IDE to just accept that the device is at 0.6.0? I can’t connect to the device physically to update it right now.

One way would be to flash a simple (empty) 0.5.2 firmware to force a refresh.
