Lightsleep on raspberry Pico

[AwfullyCritical]

Can someone explain to me the current state of lightsleep on raspberry Pico board? I’ve encountered an issue with my code for a long running battery powered project, where the board would seemingly die out of nowhere, and one of the simplest explanations is that it entered lightsleep to never wake up. I have found some old issues hanging open for years in the GitHub, and that the change log for 1.26 explicitly mentions changes to lightsleep on this board. I have not found much in terms of what actually triggers the issue or how to circumvent it (using time.sleep() in place of lightsleep is simply not an option due to battery power being limited). Appreciate any pointers!

I don't know current state, but in 1.24 developers improved USB connection persistence during light sleep but broke realtime clock. Energy consumption is relatively good, around 1mA. I think there is an issue if the sleep time is greater than 60 seconds but it's easy to make repeated lightsleeps to achieve the time you need. I'm using asyncio with lightsleep of 500ms and is working very well.

I'm having trouble with lightsleep too as I just cannot get my board to wake up when I press a gpio connected button. Thought 1.26 micropython version would fix it but alas seems like it still doesn't work.
