Removing a network is quite rare so this shouldn't be a release blocker. Just a highly prioritized bug.

cc: @hesterbruikman I'm removing the release blocker label and changing the sev number but please make the final call given it's related to dapps adding networks

We believe this is an issue with the Permissions Controller not updating on add/remove network. @jiexi I believe we had a similar issue on Extension that has been fixed, fixed by the permittedChain refactoring by Wallet API Platform. Do you recall what the fix was and what's needed to apply this to Mobile?
