That’s because Beirut is 60 miles from northern Israel and Tinder’s max is 100 miles IIRC. These are small countries we’re talking about here.

Phones don’t use GPS these days if they can help it - WiFi triangulation is significantly faster and uses much less battery - so GPS jamming wouldn’t have anything to do with Tinder matches.

This didn't happen before the war started.

Probably some new-age hippies at Tinder taking the 'make love, not war' manta to heart. /s
