Please tell us some basic information before asking for help:
Model Name: ASUS ROG Phone 5S Pro and ASUS ROG Phone 5 Lighting Armor Case
Firmware Version: 31.0810.1226.91
Rooted or not: not
Frequency of Occurrence: all the time
APP Name & APP Version (If your issue relates to the app): latest Armoury Crate
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
RGB Lighting on the case is not working even if it shows connected and the Lighting settings in the Armoury Crate are available and turned on. Issue started after updating to latest firmware. Please check. I also check that the connectors on the Lightning Case are clean and not bent as well as tested the RGB Lighting on the ASUS ROG AeroCooler 5 which is actually working fine. It's just the Lighting Case having issue.
