From our side it is necessary to limit the wallet API import jobs, because of restrictions set by our API providers.
Thus an automatic import is only possible for 2 wallets for a free user and 5 wallet addresses for the PRO plan.
If you don't use certain wallets very often, you can import the data once and after that delete the Wallet job again. This doesn't have influence on your already imported transactions and you can use the import slot to track another Wallet address.
Should you still require more wallet imports, our UNLIMTED plan offers 50 wallet imports.
