[Reset Cross-signing] When resetting Cross-signing on iOS, I couldn't verify with the Security Key on the Web afterward

[Phuc1995]

Steps to reproduce

1. On iOS -> User settings -> Security -> CROSS-SIGNING -> Reset

2. Then log in to this account on the Web, I can't verify with the Security Key (the Security Key is correct) as shown in the image attached below.

   

3. Everything is fine if I reset cross-signing on Web

The issue looks similar in the ticket https://github.com/element-hq/element-web/issues/26243 was reported on Web repository

Outcome

What did you expect?

Why I couldn't verify with the Security Key on the Web afterward? It seems to be an issue that is seriously affecting users

What happened instead?

When I debug on my home server, I see some discrepancies between Web and Mobile when resetting Cross-Signing:

• On the Web side, when resetting Cross-signing, there is an API call to upload keys including: m.cross_signing.user_signing m.cross_signing.self_signing, m.cross_signing.master
• But on iOS, after Cross-signing was completed, I checked the database and did not see any updates to the keys:m.cross_signing.user_signing, m.cross_signing.self_signing, m.cross_signing.master
• On code iOS, I see when resetting Cross-signing only updates "devicesigning/upload" and "signatures/upload" `extension MXCryptoMachine: MXCryptoCrossSigning { ...... func bootstrapCrossSigning(authParams: [AnyHashable: Any]) async throws { let result = try machine.bootstrapCrossSigning() let = try await [ requests.uploadSigningKeys(request: result.uploadSigningKeysRequest, authParams: authParams), requests.uploadSignatures(request: result.signatureRequest) ] } ....`

Is the iOS side missing code for "m.cross_signing.user_signing, m.cross_signing.self_signing, m.cross_signing.master"?
