### 3/5 — Update Axtro 4 and beyond timing

*2026-06-16, version 2.2.0*

Hi 
Can you update app to be able to sync clock or time with Axtro 4 and later. I found it unable to do so when I’m in a country where time is behind or ahead of Singapore eg Thailand or Korea. Can only work with Axtro 3 but that tracker is out of stock and battery can no longer hold charge. Need charging daily. Please look into this as I have feedback a number of time. Thank you

### 2/5 — Tried to check for my axtro 3 but does not work

*2025-02-18, version 2.1.3*

Tried to check for firmware update for my axtro 3_5FFC v1.0.3 but does not work, says "missing or insufficient permissions" even though my app is updated. 
Was apparently able to sync data from my axtro device. Perplexed.

### 1/5 — Link doesn’t work

*2023-02-05, version 2.0.1*

The link they sent in my email doesn’t work how am I supposed to update my watches time ???

### 1/5 — Cant’t sign in to app

*2023-01-04, version 2.0.1*

I can’t verify the sign-in link when they send the link into my e-mail. How am I going to update the time of my watch? its out of sync

### 3/5 — Reset tracker

*2022-01-31, version 1.0.3*

Can you configure this app to allow users to reset tracker when needed? As HPB users, the tracker needs resetting quite often and we have to get an appointment to reset our tracker. If it is available in this app, users can be self sufficient.

### 5/5 — Thanks for help

*2022-01-26, version 1.0.3*

Tks Staff Mika at PSC for é help
