JWT's and Session expire after 15 minutes (frontend)

I’m using Appwrite for my web app and noticing that after ~15 minutes, my user session suddenly expires—calls like account.get() start returning 401 Unauthorized.

Here’s what I’ve confirmed so far:

Short-Lived JWT: I’m aware Appwrite’s JWT has a 15-minute expiry, but even if I try account.createJWT() after 15 minutes, it fails because the entire session is gone.

Session Cookie: Looking in the browser, my app’s session cookie is set to expire a year in the future, yet Appwrite still terminates the session around the 15-minute mark.

Has anyone dealt with this mismatch where the cookie’s “Expires” date is far in the future, but Appwrite ends the session after ~15 minutes anyway?

How can I configure (or refresh) the session so it remains valid beyond 15 minutes without forcing the user to re-log in?

my edge case I'm running into is when the user who wandered around the web app successfully steps away for 15+ minutes then comes back, and clicks a button that sends a request to my backend (with JWT) has that request fail.

the only trick I found to make it work again is to manually refresh the whole page/webapp at which point everything works again.
