As of v1.0.36, Core mobile fully supports Cross Chain Transfers between the Avalanche primary network chains (X, P and C). In the same release, the Stake tab was redesigned. As a result, the Claim flow was deprecated.
The rewards are automatically funded to the designated rewards address at the end of a staking transaction (if uptime requirements are met). Claiming was a feature that allowed users to import P-Chain AVAX back onto the C-Chain. Now that users can directly swap between X, P and C-Chain, this feature is no longer needed.
Please see this article, for a guide on performing Cross Chain Transfer in Core mobile.
