Heating schedules

Good morning, I have an inkbird itc 308 wifi and have set it up to run two schedules a morning and a night schedule. The first day it worked fine changing the presets to what they have been set at, but on the second day they have stopped working. I am connected to the inkbird via the app but for some reason the schedules have not kicked in ? So I have had to change the sv temp manually this morning from the app. Any suggestions please, would a reset to factory on the inkbird and then reset everything br something to consider ?
