I’m sorry to hear you’re having issues with local pickup and delivery. Let’s work on this together.
I see that you mentioned that you moved all your inventory to your one location. Does that mean you had a different location set up previously? If so, you may be experiencing a known bug. I recommend first trying these troubleshooting steps (whether you had a previous location set up or not):
Navigate to Settings > Shipping and delivery
Scroll to Local Pickup and click on Manage next to your location
Uncheck This location offers local pickup and hit Save
Check This location offers local pickup and hit Save
Repeat the same steps under Local Delivery (turning off local delivery, clicking save, and then turning it back on)
This may resolve the issue. If it doesn’t, would you be able to share screenshots of your local delivery and pickup settings? You can blur/cross out the addresses if you’d like.
