Streamlit rocks! :grinning:

The new display text feature is awesome. Links open with a single click and my dataframes look much cleaner now!!

Thank you!

Not sure if anyone else has experienced this issue or not, but I’m noticing some issues with the new st.switch_page feature. Some of the pages are not loading correctly or completely when switching between pages.

The feature works great with the exception of a couple of pages. Links are provided below. Please let me know if you have any questions.

Hi @REPNOT. If you’re encountering a bug with st.switch_pages can you check out issues in the GitHub repository. If there isn’t a current issue to upvote and comment on, then creating it there will be the best place for engineers to triage. :slight_smile:
