Limit to 80% broken with March update?

It says "Done Charging" under battery but still keeps charging... :(

Anyone else having the same issue?

Regards

Edit: I trickle charged it (after reaching 100%) until the "protection" sign appeared, will report back if 80% limit now works

Edit 2: I can confirm it still works. You must let it charge to 100%, but do not disconnect it immediately. Wait until a protection/shield icon appears next to the battery icon in the top bar. Using a USB power meter or power bank, you will see that it stops drawing power only at that point.
