Walmart pickup 'something went wrong please wait a few minutes before making changes to your order

Walmart and app site keeps crashing.  I will miss my cutoff time and not get all of my items. This will defeat the purpose of grocery pickup because I will have to actually go inside of a store for the items I couldn't get. Please fix this glitch. It is inconvenient, especially during the holidays. Thanks

The site keeps crashing when I try to add things to the grocery cart. It has been saying for two days that I need to wait a few minutes before adding items and they just keep sitting in my cart. I tried taking everything out and Readding them but it still says I need to wait a few minutes and it never starts working again.

Keep getting, "Please wait a few minutes before saving changes to your order." have tried for the last hour, but no luck.

There is NO EDIT button on my Walmart app, please fix ASAP
