Observation: something in .log files may cause the Competitions page to update slowly. Inside the folder UserData\player\LocalStorage\IndexDB\http_localhost_397.indexedb.leveldb\ remove the log files having extensions .log and .ldb then the Competitions page returns to normal update speed with a new .log-file file of smaller size. To test, I restored problematic .log file replacing the good 000003.log file and Competitions page was slow to refresh; removed problematic log files and Competitions page returned to normal again. This observation also noted in Discord within #open-cs-series channel. Alternate solution for players: in UserData\player folder rename LocalStorage folder to something else. (edit removed link March 13 --no longer needed) link to my two problematic log files zipped at (edited to replace "large" with "something in") -- file size may be irrelevant ~David Shrock (DracoTorre)
Appears solved. Update to CS reported on Discord issue was "how cache was saved and transferred" https://discord.com/channels/253557076645773312/791309271471095818/948223549942923284
