acsm files won't open on chromebook/android

Question

My Adobe Digital Editions will not open acsm files on either my chromebook or android phone any more. I have deauthorized, uninstalled, reintalled, and reauthorized ADE multiple times without change. I have wiped and reinstalled the operating system on the Chromebook, and that had no effect. Dragging and dropping the acsm file into ADE does nothing. When I right-click and choose 'open with' ADE is not an available option, despite having set ADE to open associated file types in the settings.

This problem arose within the last week or so (I noticed it on Saturday when I tried to open a new book), and I cannot find anything online that helps. I am currently on Chromebook OS version 109.0.5414.125 and ADE version 4.5.11.187425. I have exactly the same problem on my Pixel 5a, which is running Android 13, although I have not wiped and reinstalled the OS on that device.

Any help would be appreciated. I use an ebook and read for a few hours a day, and I'm running out of books.

So far, it is still a problem on all my devices, but I did find that, cx file explorer, which is a 3rd party android file manager, does recognize that acsm files are associated with ADE and will allow me to open those files.

I'm still rather unhappy with this workaround, but I can at least get it to work. It suggests to me that it is Android/Chromebook's file manager that may be at fault. But, having wiped and reinstalled the whole OS on my chromebook, it also suggests that ADE is not associating itself properly with acsm files either.

I'd appreciate any further help. I just wanted to record my workaround here for anyone who encounters the same problem.
