PIM Product Timing Out🔵Error Handling

I was doing a bunch of testing on the PIM this AM with my company 'Del-Tap' and I tried to load a very large product list. I ended up have an upload error (which is fine as it was an aggressive size), however now it times out every time I try to go back to it. Not sure if there is still stuff going on in the background on the profile, as I switched to my other test company and I can enter the PIM. Want to ensure that if a user experiences the same issue that the backend resets so it doesn’t take down their PIM. Likely a technical issue.
