I have this problem since I’ve got the Pebble Time from a friend not long ago.
Anytime I get a WhatsApp message and try to reply the watch automatically get stuck for few seconds and restart it self.
I tried to factory reset it and that didn’t fix the issue.
I have pebble time with V4.3-rtl-r0 firmware and using an android phone Xiaomi Redmond 4x.
Did anyone had this issue and know how to fix it?
