Custom GPT wont keep web browsing enabled . I can get it to work only in preview.

I’m currently facing a challenge with enabling web browsing in a custom GPT model. While I can successfully use the web browsing feature in a preview mode, it doesn’t seem to work when I switch to the standard operating mode. This limitation is perplexing and I’m looking for insights or solutions to address this issue. It’s important for the functionality of my custom GPT model to have web browsing capabilities fully operational outside of just the preview environment.
