I bought Notify and Fitness pro version approximately a year ago for mi band 3. A few months I have mi band 4. I download EMOJI SUPPORT FONT FILE from Notify and fitness. After that my band's default watch face shows calendar wrong. For example 02/12 true but my band shows 0212. It hasn't this "/" symbol. I download and flash original font file Font_V1 from geekdoing but my problem didn't solve. I made factory reset my band but it didn't work. What can I do for this problem ?
