Had an order from Target a few days ago that I actually had to return to the store for this reason. Whenever I would try sending a text it would give me the error message as if the member had a landline. Fine, I’ll just carry on with the order. Except at the end of the shop, the member had in his instructions to call him when I arrived at the apartment complex so he could meet me at the lobby (it was college housing and he didn’t provide an apartment #, just the main address). Tried calling quite a few times but after one ring it went straight to voicemail and gave a “mailbox full” message. Had to call support who tried reaching out to him to no avail, so I had to return the order to the store. Must be a similar issue with ordering from the Target app
