Overview
Use this guide if you try to open the register and:
- You tap Open Register in the menu and enter your opening amount.
- You tap Open, and the window closes — but nothing happens.
- The menu still says Open Register instead of View Register Session, no matter how many times you try.
The most common cause of this issue is that your iPad's date or time is wrong. If the iPad's clock is behind the real date or time — even by a day — the app can't tell that your new register session is the most recent one, so it keeps showing the register as closed.
Step 1: Check the date and time on your iPad
- Look at the date and time in the top corner of your iPad's screen.
- Compare it to the actual date and time (check your phone or a computer).
- If the date or time is wrong — even by one day — continue to Step 2. If it is correct, skip to If the issue continues below.
Step 2: Fix the date and time
- On the iPad, open Settings.
- Tap General.
- Tap Date & Time.
- Turn Set Automatically ON. If it is already on but the date is still wrong, turn it off, set the correct date and time manually, then turn it back on.
- Confirm the Time Zone is correct for your store's location.
Step 3: Restart the Material POS app
- Swipe up from the bottom of the screen and pause to open the app switcher.
- Swipe up on Material POS to close it.
- Reopen Material POS.
Step 4: Open the register
- Open the menu and tap Open Register.
- Enter your opening amount and tap Open.
- The menu should now show View Register Session, which means the register is open.
If the issue continues
- Double-check that the iPad's date, time, and time zone are all correct.
- Restart the iPad itself: turn it off, wait 10 seconds, and turn it back on.
- If you still can't open the register, contact Material POS Support. Let us know you already checked the date and time — we can check your register sessions on our end and clean up any duplicate sessions created while the clock was wrong.
Good to know: each time you tapped Open while the clock was wrong, a register session may still have been created behind the scenes. Support can close out any extras so your reports stay accurate — just mention it when you reach out.
