Ever since 1.24 came out I think its when the issue started.
Normally admin-logs are updated every 5 min, but now
ever since newly installed server admin log refresh delay can go up to 30min
sometimes 5 min delay (that's normal), sometimes 10min, 15, 20, 30

It does not seem to be Nitrado end issue.

My old server that hasn't been reinstalled or anything after 1.24
its admin-log refresh delay is 5min always as it should.

My new server reinstalled after 1.24 ended up with the issue.
Support tried many things to resolve it, but nothing worked.
Also since Nitrado has reinstalling issues i closed the server and got new server
but the issue even with week old server still has same log issues.
