Claude FAQ: Slow Loading, Lost Context, and Handling Attachment Formats

This roundup is a Claude FAQ, focused on resolving the small issues that most often get people stuck during use: slow page loading, conversations seeming to “drop” context, and attachments that won’t open or display with messed-up formatting. No mysticism—just a step-by-step checklist and practical alternatives you can apply immediately. Follow the steps to troubleshoot when problems occur, and you can usually restore a normal Claude experience quickly.

What to do if the Claude page loads slowly or keeps spinning

When Claude loads slowly, first rule out browser-side issues: if refreshing still doesn’t help, switch to an incognito window or temporarily disable ad blockers and script-manager extensions. A lot of “spinning” is actually caused by extensions blocking page resources; after disabling them and logging back into Claude, it usually works normally.

Next, check the network path: on the same network, switch to a mobile hotspot for comparison to quickly determine whether it’s your local network or site-side fluctuations. If Claude only acts up on a particular Wi‑Fi, prioritize restarting the router, clearing the DNS cache, or switching to a more stable network and trying again.

Claude replies more slowly, answers get shorter, or it seems not to understand the context

Claude’s context depends on what you’ve sent in the current conversation: when the information is too long or the structure has too many layers, the model may prioritize “the most recent few messages.” The fix is to compress the key requirements into a single “task brief,” put it at the beginning of your latest message, and list the rules that must be followed as bullet points.

If you change topics frequently within the same conversation, Claude is more likely to go off track. In that case, it’s recommended to start a new chat and copy over the most important conclusions from the old one as the new starting point for context—this saves more time than trying to patch things up in the original thread.

How to handle Claude attachments that won’t open, have missing content, or look misformatted

One of the most common items in Claude FAQs is attachments: being able to upload a file doesn’t mean it can be parsed reliably. Prefer more universal formats (such as PDF or plain text), and avoid stuffing in too many images at once or extremely long documents; split large files into several parts before uploading, and Claude’s reading will be more stable.

If code blocks or tables are misformatted, explicitly ask Claude to “output in Markdown” or “output as a three-column CSV,” then have it double-check the number of fields. If you need precise alignment (such as table column widths or indentation), paste a snippet of the target format as an example for Claude to follow—usually it can be fixed in one go.

What to do if you can’t find chat history, or you’re worried about content leaks

If you feel your Claude chat history has “disappeared,” first confirm whether you switched accounts or browser profiles (work/personal, main browser/incognito windows are often mixed up). The same Claude account generally syncs across devices, but abnormal local caching can also cause the list to not display temporarily; re-logging in or changing networks often brings it back.

When privacy is involved, the most reliable approach is to reduce sensitive information at the source: replace names, phone numbers, order numbers, etc. with placeholders before sending them to Claude. If you truly need to paste business data, send only the necessary fields first, and clearly tell Claude at the end: “Process only what I provided; do not extend or infer beyond it,” which can reduce unnecessary associations and misuse.
