My phone coverage stopped for a period. I was using connect at the time and a comment failed. I initially thought it was a big but noted after restarting, it still was out. Then I checked with a test search to find it was all internet.
A few minutes later internet was back. Went back into Lemmy and refreshed. No data showing. I checked down-for-me for my instance and it was up. Refreshed again. No data.
Again restarted app and it was fine then. So, it seems he connection outage did not allow refresh after it came back, despite a restart during the outage.
