Cannot resume stream because SMID was previously deleted (no_previous_session_for_smid | XEP-0198)

MongooseIM version: 6.2.1
Installed from: image
Erlang/OTP version: 26

Hey 👋🏻

I'm trying to implement stream resumption, and even though it works most of the time, there are cases where I receive this element:

<failed xmlns='urn:xmpp:sm:3'>
  <item-not-found xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
</failed>

This is because MongooseIM cannot find the SMID, but it's not clear the reason.

Example in the logs:

Not sure if I'm missing something here. Any help will be appreciated! Thanks. 🙏🏻
