WTH — app sucks

I couldn’t access to my account’s online purchases & orders

Costco warehouse is great The Costco app the checkout process and especially the service is trash

The customer service in the app is absolute trash

Add to cart - non functional

Despite multiple updates done, add to cart function does not work.

Costco’s Great! The App Not So

The Costco App appears to work well when shopping for items, etc. However, the “ Account” feature is spotty at best if you want to pull up previous receipts. It keeps spinning with no success of being to pull them. This is even after I deleted it and reinstalled the App.

Keep crashing

Since iOS 26 this app has been not functioning correctly

App crashes

App still crashes every time I try to open it

Pls fix Orders and purchases tab

Loading and display error. Pps fix. Cannot view “orders and purchases” in the app

Poor mobile app

As long standing customer of Costco, I believe their that as a company it is great and their products and service are excellent. But their mobile app is very poor. It feels like decades old app and app features are very poor

Does Not Load!

2026-09-18: After last week’s update, App no longer loads on iPhone X (iOS 16). Costco made another update this Wednesday, and it still refuses to load. Anyone else with this issue?

App crashes

App continuously crashes and will not open even after updates and deleting and reloading

Removed all product information

All product information now only in very tiny product information windows.

Fix bug

Its several days trying to get access to my orders and purchases, never loads and page stills spinning

Best store

I love this store it’s like my second home !!!

Cant even use feedback function for broken app

Better off with the website… painful to scroll and look at items. The back and forth as well as cart management is poor and dated. Really got mad that i couldnt easily switch warehouses and went in circles. My wife had the same issue…

Dont even get me started on the account management side of things… tried to report these issues in app and the app shuts down. Embarrassing for how much money this app brings in. Please invest in your UI/UX.

Not working

Not sure what they did but I can no longer get this app to open on my iPhone!

Cannot access past orders - waited 2+ minutes

When I try to see my past orders, I never get to a screen where I can choose warehouse or online orders. Progress bar moves forward and backwards for over two minutes before I gave up. I force quit the app several times to no avail. I also force quit every other app on my phone and rebooted my phone. Still didn’t work.

App sucks

Can’t even see recent orders. Doesn’t load

Terrible App

For a company that makes billions of dollars in revenue a year. They sure can’t figure out how to make their e-commerce app or website functional it crashes all the time takes really long to load and buggy. Makes me want to stop shopping every time I use it.

Crashes

Recent updates are causing app to crash/ close when trying to open.
