Portfolio object has no attribute checkCryptoChallengeSubmission

This did not generate and error yesterday, today it does. Any idea ?

Updating the solution you found for others to see.

Found the solution for whoever also face the issue : replace ‘’‘port.checkCryptoChallengeSubmission(maxIter=10)’’’ with ‘’‘port.checkCryptoSubmission()’’’
Apparently the first function was removed today so it’s no longer usable
