I took on a gas station assignment and now that I’m 75% through, there is a glitch on Presto and when I click into the assignment, it says that the app is down for maintenance. If I uninstall and reinstall the app will all of my data disappear?
If your shop is going to time out before the maintenance is done you'll lose it. But if you have the time, just wait and finish your shop when it comes back online. There is nothing to be gained by deleting and re-installing the app.
The site is back up now. They do these things as quickly as they can but it's a real bummer if you grab something time sensitive and can't finish it because of their maintenance needs.
