Map geocode doesn't always work

I love this feature. I have a table with the recommended columns and a map widget below and it generally works. But sometimes when I put in an address and toggle to geocode, nothing happens. It consistently doesn’t seem to work on addresses with unit/apt. numbers, which isn’t ideal but I can fix it by deleting that info. Wondering if there are other known cases where it doesn’t work, or how I can figure out what’s causing the problem (is there a log to check?) or how to force/reload the script.

Something else I noticed - if one row doesn’t work for some reason, it becomes a bottleneck and nothing entered after it will work either. Once I manually fixed the coordinates for a couple addresses, the rest filled in.
