All of a sudden today the USB-C ports in the back of my 2020 iMac running macOS 11.1 aren't charging my 2018 iPad Pro. It's providing enough charge to maintain the current battery level but won't increase the battery level. If I unplug from the iMac and use the regular iPad Pro power brick plugged into a wall outlet it charges normally. Thanks.
iMac Line (2012 and Later)
Please reset the SMC 2-3 times back to back with all external wired peripherals disconnected and then retest. If the problem persists please reset the NVRAM.

It took doing the SMC Reset several times, but now the iPad Pro seems to be charging fine through the iMac so for now we're good to go. Thank you!
Your welcome.
