Thanks for your help. As indicated in my original message, I've already done both of those things plus several other common troubleshooting methods. 

Couple of Suggestions for you.  Double tap home button and turn off all apps. Turn on Airplane mode.  This shuts off all radios and works as a reset.  Go to Settings/Point of Sale and make sure Cell Data is turned on. Make sure you have the latest iOS.   What iPhone are you using?  Otherwise it sounds like you have done everything else.   Very strange.

Thank you so much for your suggestions! It actually turned out to be a problem with connectivity in my area and timing out on the login screen. Not sure what I did exactly but something you suggested worked because it logged me in soon after. 🙂 Thanks for taking the time to reply to my question!

sorry, I just saw the question and was answering on my phone at break.  I'm stumped if these steps didn't work.

No problem, I really appreciate you taking the time to offer suggestions to help! 🙂

Thanks very much - I was able to get it working again. Sorry for the delay in responding, I didn't realize there were responses to my question here. 🙂

Happened to our salon for the past month. It is a system error they are having, I have been on the phone non stop with the support teams for appointments and with the P.O.S manager Wendy.

Because the enginieers did not fully test out the new upgrade, that combines both Point of sale and appointments. It has created a huge malfunction for anyone to sync and connect their accounts.

I have gotten the run around for about a month until support team member Mannie finally told me that they were having severe issues with this. 
To be honest with you, sign up with a different appointments program. That's what we had to do.

Also to add in, our security was breached during this upgrade. Meaning that independent contractors were able to log in and view our business account by a simple click. Despite them having their own accounts, the appointments app had linked their money into our bank accounts. Which is illegal.

None the less, please save your self some time if you haven't figured it out yet and find another appointments application. You will continue to have issues until the engineers fix all  of the bugs.

hi @Entourage - I'm really sorry to hear of the problems you've been having. While our issues are similar, I was able to resolve mine by altering the connection settings in my wifi / data panel. I don't think this will remedy your situation but I hope that you get things straightened out and don't have to switch providers.

Hi @DeannaC - my issue ended up bein a connection problem and timing out on the login screen. Try making sure that your cellular data is enabled for Point of Sale in your apps. That might help.

Hi Saff,

I ended up deleting and reloading the app 2x before I could click on the icon and have it take me to my account. Very strange.
