# YFinance > 0.2.28 support in Community Cloud

# UPDATE 2023-10-01 This has been fixed with yfinance>=0.2.31b2

## OLD:

yfinance changed the default behavior in version 0.2.29 to cache timezone info to

improve performance. However, the default place it tries to save the cache

(`/home/appuser/.cache/`) doesn't exist on Streamlit Community Cloud.

You can get around this issue and still use the latest versions of yfinance by setting

a different cache directory than the default one, like this:

```python

from pathlib import Path

import appdirs as ad

CACHE_DIR = ".cache"

# Force appdirs to say that the cache dir is .cache

ad.user_cache_dir = lambda *args: CACHE_DIR

# Create the cache dir if it doesn't exist

Path(CACHE_DIR).mkdir(exist_ok=True)

```

This puts the timezone cache in a new folder inside the current folder, called .cache

```

streamlit_app.py

.cache/

  py-yfinance/

    tkr-tz.db

```

`.cache` isn't really special, but it's a writable location -- you can name the folder

whatever you want.

This bug has been reported here https://github.com/ranaroussi/yfinance/issues/1700

This app can be previewed at: https://yf-fix.streamlit.app/

Alternatively, you can set `yfinance==0.2.28` in your requirements.txt to avoid this

issue.
