For once, the problem does not seem to be confined to people using telephones. I am seeing occasional delays of from about 10 to 45 seconds running Firefox on a Win 10 machine. We have also noticed an increase in duplicate posts that I have concluded are caused by people trying to save a post, encountering the delay, and clicking on the Save or Post button more than once. All that I can say is that the people who own the server farm are working on the problem.
