Unable to update Lr for Android beyond 8.2.3

[mikerbiker58]

My Samsung A13 worked fine until the recent updates. Google Play store and Creative Cloud both report that my installation is up to date, but Lr About Lightroom reports it is 8.2.3. What's New describes 9.1 features.

I have reinstalled, rebooted etc., but cannot get it updated, and now there is no edit functionality, as an editable file will not download. All library albums are visible, and the app shows everything is synced and up to date. Local storage reports in Lr as cache and app data empty.

Thanks Rikk.

It has an Exynos 850 octa core processor, 4Gb ram and 64Gb storage, so exceeds minimum requirements.

Strangely, 8.3.2 will download and edit old smart previews, but not recents. And the phone shows the memory and cache usage, whilst the app says it is not using any storage either for the app itself, nor for app data, despite displaying 32k thumbnails! Images shot on the phone using the Lr camera are fully usable, but nothing that has been touched by up to date Lr versions on other platforms since October.

Time for a new phone, I suspect.
