(XANADU Patch 😎 In flow designer, after modifying an existing working flow, it is saving but not activating, it gives the error:
INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified
There is no custom actions or scripts used, only OOB actions like asking for approval, updating record and sub-flow etc.
And after removing the change to make it as before, it still giving the same error and not activating.
I checked almost everything, it is for this flow only, activating on test instance without any error, tried clearing cache.
