I can't access IITC it won't let me log in it keeps saying login failed and I'm not the only one.
Good it's unofficial and shouldn't be used,,
Remove plugin and visit intel.ingress.com then report
niantic cant give support on something they havent developed.
Can you log in to straight stock Intel?
99% of the time login issues have nothing to do with IITC, and everything to do with Intel, such as Facebook login issues, banned accounts etc.
I suggest @NianticBrian or @NianticThia or even @NianticVK Close this topic as it's not an official product of Niantic's so not really a bug that needs reporting or Actioning.
However support should be directed towards the IITC Makers.
