I have been unable to succeed in the VERIFYING CONTRACT step when I deploy the contract to the main network.
The page prompts "It’s taking longer than normal to verify your contract deployment 
. Please check back again soon. If the problem persists, please report this problem on our forum at https://forum.manifold.xyz/ "
This should be resolved now. There was an issue with etherscan earlier. If not, please post your deployment transaction and we can investigate.
