The app is now upgraded to latest genosdb. Please use the button on home screen which will do the following

1. load both the new and old DBs separately
2. login to old DB using current mnemonic phrase
3. load all old notes to the new DB
4. clear DB, OPFS storage and logging out from old DB

This should not have any errors, i've added some guardrails to not clear data when it fails, if it does pls LMK.
