For this feature to be implemented, the database structure changed. The old database with the new code could leave a blank screen. Hopefully this never happens but if you see the screen below, we have tips just in case. For some reason, your database has not been replaced with the new one. (A slight possibility of a glitch like this is a trade off for having a local database that works offline.)
Please also read the in-app section on Database Updates. Having the latest database and a proper restart should fix it. However, the most thorough option is to delete the app, restart the device as in power off and back on again and redownload (select app to buy but Apple knows you bought it so they will say it's free) and install the app again. This takes care of any update glitches or bad database downloads that have happened to a couple of people. Please let us know if this is the end solution so we are aware of it and how often it occurs.
Select the app and hold the icon until it wiggles.
Tap the X
Find the app in the app store and act like you are buying again for the first time. But it's free...
Then install and update the database if there is a update, waiting for the finish prompt to know it's done.
AllStays Pro keeps getting better. We have always received a lot of requests for full screen maps for computers, GPS downloads, Google Earth offline and many other things that couldn't be done either by app or a advertising support website. So this new service helps with that. Along with full screen maps, we add more filters by price, stars/reviews, elevation, weather layer, traffic layer, biking route layer, transit map layer and more. AllStays Pro is here.
