Though Bitcoin cash is being promoted as an alternative to Bitcoin due to the lower transaction fees, in reality users are finding it difficult to receive Bitcoin cash  payment. For example one website is paying its partners using Bitcoin cash.
Since the amount can be withdrawn directly to the bank account using Coinbase, some users are interested in using bitcoin cash
However, when the user is trying to save the Bitcoin cash address in the form provided by the website, it is giving a bitcoin cash error as shown in the screenshot below
The error was noticed using Google Chrome browser on a Windows computer
Despite wasting time saving the address repeatedly, after copying the address from Coinbase, it was not saved.

Though the user wanted to use Bitcoin cash, she was forced to use other online wallets.
Are other Bitcoin cash users also facing this problem saving the bitcoin cash account number for their account?
