Occasionally when browsing SharePoint and PowerAutomate sites I get an automatic save file prompt asking me to save "preload". This happens on all my profiles, and in Safari too but not other browsers. Browser settings for file download location should be set to "ask each time" for this to happen.
To replicate:
open SharePoint or PowerAutomate sites. Click around for a few seconds, or minutes.
The issue happens intermittently (sorry!)

Not to be asked to save a "preload". Doesn't seem like it's meant to do that.
