niantic perform agressive filtering of short links - so no point in waisting time in IITC testing link length too
reduce the delay between requests - now we always send 4 at a time, rather than larger batches, a shorter delay is better
quick fix for capture date removal - could do with re-formatting the sidebar data to use the space better
allow a higher number of tile retries if the config value exists in the stock site
