Location services, address incorrect

So…..I updated my location and now it shows accurately. Then I updated my husband’s location on his devices, which had the same bad address I had, and now his location also shows accurately. Yet his location on my app shows the old inaccurate address for him. I turned my location services off, waited 20 secs, and back on. Then I did the same for him. His address still shows inaccurately, but only on my app, not his. What now? The thoroughly exhausting constant trouble-shooting of tech. Please help, I give up.
