Attempting to upgrade Terracube 2e from version 1.0 to 1.1 (2020 model)

Hi Alexis, I also just noticed that v1.5 has been posted on the updates page for 2e, and that it has appeared as a download option in my OTA updater (screenshot below). Is it recommended that we try this, or should we wait for sideload instructions?
[edit] - Ah, I think it was automatically included in the updates for all phones, then taken down. It’s no longer there, which I interpret as /e/ not endorsing its use.
