i m having problem migrating my program to be able to use in the new blynk app. ive tried adding the template id, device name, as well as the auth token and it seems to connect. but the problem is, it wont work like it used to in the old blynk app. the data wont be displayed on the lcd. what should i do? thanks for those wholl help
#define BLYNK_PRINT Serial
