I use very few apps outside of the stock GrapheneOS install, maybe three or four. Two of them have stopped working properly after recent updates, they were working fine before and work OK on other non-GOS phones.

Simple SMS messenger will not show images when selected, the stock messenger works fine

IO Shopping List (which is important to me, it's easy and works great, doesn't require a server) won't convert to CSV so I can store lists for backup.

Both had been working as recently as a week or so ago, Re-installed Simple SMS but did not resolve problem, did not reinstall list app for fear of losing lists.

Checked permissions but didn't see anything that would cause problems.

try enabling "Exploit protection compatibility mode" for those apps

in the same place where you find permissions for every app, just scroll down
Settings/Apps/See all apps/YOUR APP

kellyv long press on an app and press "app info"

The option to turn this function on is about midway down

Try disabling Enabled secure app spawning in security settings and enabling native code debugging

Thanks - didn't make a difference

Well, don't know what else to recommend you. I just tried installing OI shopping list (not IO as you listed) and it worked out of the box.

Are you able to convert to CSV? That's when it crashes for me and I am unable to save the list. Thanks

Just wanted to add - I have two older phones with Android 7.1 works on one but crashes on the other
