Hi Phil,
I did find that the new version of survey 123 seems to work for my phone (Android Galaxy S7) after reinstalling the app and then reinstalling the surveys. Unfortunately, the bug still holds true for the tablets we are using out in the field (Android Tab A 2019). The problem is we could not wait for a fix to be implemented to the new app, so at this point Survey 123 Classic was our only option. However, everything seems to be working just fine. I downloaded the Survey 123 Classic Connect app and then downloaded each individual survey and re-saved the forms using Connect Classic. I then re-downloaded each form to the Survey 123 Classic app on each tablet.
One of the other odd things that happened to our forms as a result of the bug on the new version of the application is that we lost our radio button appearance for several fields. They reverted to drop-down menus and no matter how many times I tried I could not get them to appear as radios again, perhaps this was due to changing the name of the appearance property that causes those dropdown boxes to appear as radio buttons or maybe it is just a compatibility issue, but it seems that when we reverted to Survey 123 Classic, this functionality returned.
Our forms are fairly simple and straight forward and I made sure to test one of them by sending an entry to our database to make sure the data reached the server. Everything appears to have worked fine and the offline maps are showing for our geopoint fields.
