Did personal hotspots suddenly get throttled/deprioritized?
My wife and I use personal hotspots on our phones for gaming, along with a dedicated hotspot router line. This worked great until a few days ago. We're on a new billing cycle and are NOT anywhere near the cap where it would start getting throttled. Both hotspots (hers Galaxy S9 mine iPhone SE) suddenly started being super super laggy, to the point that the same games that worked last week are unplayable. However, the dedicated mobile hotspot router on its own data-only line is fine.
Did personal hotspots in particular or xbox live on those suddenly start getting throttled?
