I Just create a Corporate-owned devices with work profile in our Endpoint Manager by following the link down below:
How to configure Android Corporate owned, personally enabled user devices with Microsoft Intune
On tap of the article, I add the following additional configuration settings in configuration profile:
Allow auto update during maintenance time 6pm - 9am
Minimum Password length: 6
Then edit 1 field in the compliance policy down below:
Minimum Password length: 6
After all that, I was trying to test it with a Samsung LTE Android tablet (I didn't have a cellphone available at that time), everything went well (scanned barcode and installed required apps) until register device via Intune, then I gets this "We couldn't complete sign in" message as the following screenshots :



I clicked retry couple times, still not able to pass this page, but the device showed up in my Intune group as Android enterprise devices. Could anyone please suggest me how to solve the problem?
Thank you in advance.
Nathan
