I've been trying to implement Azure B2C as an identity provider.

After following the docs https://docs.microsoft.com/en-us/powerapps/maker/portals/configure/configure-azure-ad-b2c-provider

but if i click the azure b2c button i get a sign in failed message

Looking in at the network traffic, i see the following error
AADB2C90057:+The+provided+application+is+not+configured+to+allow+the+'OAuth'+Implicit+flow.Correlation+ID:+4ff2d37b-1025-4f4d-91e8-e9f9a292d19bTimestamp:+2020-11-10+15:01:45Z

anyone have a idea as to what I'm missing? I've tripple checked all my settings by now.

Hi @joeristroy are you still having this issue? I am having this issue and I tried following this guide:
https://docs.microsoft.com/en-us/powerapps/maker/portals/oauth-implicit-grant-flow#turn-implicit-grant-flow-on-or-off
Basically I had to make the following keys:

Of course, this did not solve the issue for me, but maybe it might for you. If you were able to find a solution, please let me know, since I am still trying to figure it out!!!
