I have since gotten it to work. I believe that I had previously made the mistake of having both ODK and KoBo on my phone, and when you select a blank form to fill, ODK and KoBo will both ask you what software to use to edit the form. I believe I made the mistake of selecting “always use odk” and not “just one time”, and this seems to have broken KoBo. Now that I have reinstalled ODK, I get asked about the form again and I can use both ODKcollect and KoBocollect. While my problem is fixed, I must say that it is a little bit annoying to have to select that every time.
Regardless, in case it is useful to you, I answer your above questions:
KoBoCollect is ver 1.25.1
Phone is Pocophone F1
Android is Resurrection Remix 7.0.2 (Android 9)
Thank you for your time!
