It is lack of RF power for many stations!
Furthermore there is a big difference between 2200m and 630m regarding
propagation above sea water and above land. There have been just a few
WSPR decodes on 630m by russian RX stations while they are getting very
good results on 2200m. That explaines the advantage of living near the
sea. In other words, it should be relatively "easy" to get some TA
detections by stations living near the sea, however it is much harder to
get the same results when living a few 100 km distant from the sea...
