No, external funds will not be updated automatically every 90 days on Groww. If you have linked external investments (such as mutual funds held outside of Groww), you need to update them manually.
To update them:
1. Go to the dashboard section of mutual funds.
2. Scroll down and click on the 'Refresh external Fund'.
OR
1. Go to the Explore section of mutual funds.
2. Scroll down a bit and tap on 'Import Funds' under the 'Quick Access' section.
This will allow you to refresh and update your external mutual fund investments. This ensures your investments are up to date, but it requires manual action.
You can also update your external investments by clicking on the 'UPDATE STATEMENT' button below.
