Transaction Rejected after chain switch

[JaySecurity]

When making a purchase a user has options of a token on ethereum or base. As part of the purchase logic the current chain is checked and if required eth_switchEthereumChain is called. in the case when this request is made after completing the switch metamask mobile app closes and the eth_sendTransaction gets called and rejected without even opening metamask. The same behavior on desktop works fine.

Using "@metamask/sdk-react": "^0.30.0", Brave and Firefox mobile browsers and metamask mobile app on android, all updated to latest versions.

Any thoughts on what might be causing this would be appreciated.

Cheers

Hi @JaySecurity !
Are you able to share a part of the code for that interaction?
For these sorts of interactions we suggest the use of metamask_batch where the first request is the wallet_switchEthereumChain and the second is the eth_sendTransaction. The call for eth_sendTransaction should not be programatically made to avoid having the deeplink blocked by the mobile OS.

I'll try to get some code available to share and I'll have a look at the batch option. I've had to jump over to another project for a few day but I'll update as soon as I get a chance. Thanks for the response.
