I visited Nicaragua from 8 April 2019 until 28 June 2019, 80-some days.
I spent almost all my time in Matagalpa and on a coffee farm outside of San Ramon.
Everything worked out fine, no trouble anywhere, never felt endangered or threatened in any way.
The ATMs all worked except one that was always out of cash in Maxi Palí. The stores all had stuff, the gas stations all had gas and the buses all ran more or less as expected. I could not see or feel any difference from any of my other trips to Nicaragua. Except one of my two favorite hostels was a little smaller and had dropped their prices a little and one of my two favorite restaurants had gone out of business.
