19.38 trouble sideloading app

So you’re able to sideload a starter app but not your own app? By starter app, do you mean an SDK sample, or do you mean an unmodified app created by "Monkey C: New Project"?

When you look at \GARMIN\APPS\LOGS\CIQ_LOG.* on the device, do you see an error message (such as “signature check failed”)?

Is it possible that you’re at the limit for apps on your device? (I realize this is unlikely given you’re able to sideload the starter app). You can check the number of installed apps and the limit in the Connect IQ phone app. You can also use the same app to delete any previously sideloaded apps.

The big changes related to sideloading that I’ve noticed with firmware updates on my FR955 over the past year are:

- all app types are now “hidden” (made completely unavailable) in the file system, rather than just most app types

- it doesn’t seem possible to sideload apps that were built for a different device type anymore (e.g. an app built for fr935 won’t sideload to fr955, afaik, although that def worked when I first bought my fr955)

 I have reverted back to a previous version of my application. It seems in the newer version the items weren't being identified. I don't know why it impacted sideloading, but this implementation does everything I need. to answer your questions  I tested using an unmodified app created by New Project and I delete and resideload apps every time. I really appreciate your help.
