Welcome to the Community, Tina white.
Unexpected issues in QuickBooks can sometimes be affected by the amount of data stored in the cache. This is because a regular browser will constantly overwrite the data and will not remove history unless done manually. Make sure that your chrome is updated. You can also log in to your account through an incognito window. This mode doesn't store cache that's why we recommend using it.
If it works fine, we can clear the cache of your regular browser. This helps remove any browser-related issues and refresh your browser's settings.
If the same things happen, I recommend contacting our Customer Care Team. This way, you'll be notified once any updates on this issue and follow up your case.
For your reference, here are some references that you can check out about adding attachments QBO and what are its supported types:
