Olm sessions broken by use of outdated cache #7790

Closed richvdh closed 1 month ago

richvdh commented 1 month ago

We recently found and fixed a bug in Element X iOS (https://github.com/matrix-org/matrix-rust-sdk/issues/3110) which caused Olm sessions to be corrupted due to lack of cache invalidation when control switched between the main process and the NSE process.

According to @BillCarsonFr, Element iOS suffers the same problem; we should fix this as it causes users on other platforms to see UTD errors.

Estimated as "S" assuming we just delete the crypto store cache when we come to the foreground
