Nextdns keep connecting to far servers eg. do-blr, vultr-blr. instead of close servers of Bombay

been using nextdns free tier for a while now, even made new accounts, countless profiles and adjustments to phone hostaname setting despite all that none of it matter nextdns can't stop contacting to Bangalore server instead or Mumbai servers, since Mumbai is just 300 to 400km distance from i live and Mumbai servers are always under 50 ping that's good but my nextdns account all 3 accounts I've made in order to hope to pop on Mumbai server never worked. i think there's bug in my account. my current account since i deleted previous account which didn't connect to Mumbai server. please help me btw i don't have pc or own in case you tell me run dig pc which i can't. using nextdns on android my own. thank you!
