I cannot manage folder subscriptions on my Android tablet because I cannot scroll thru the list of folders when I choose Settings -> Folders. The middle Folders pane acts as if there is no scroll bar, even though only about 1/4 of my folders are displayed.
The tablet is a Samsung Galaxy Tab S, Model SM-T800, running Android 6.0.1 with Google Chrome 69.0.3497.100
Roundcube is installed on Debian Stretch with php 7.0.30, apache 2.4.25, mariadb 10.1.26. I had originally installed roundcube 1.2.3 from the debian stretch repo, but when I hit this issue, I first upgraded to 1.3.6 by downloading and installing the .deb packages from the buster/testing repo. When that didn't fix it, I downloaded and installed 1.3.7 from here:
https://github.com/roundcube/roundcubemail/releases/download/1.3.7/roundcubemail-1.3.7-complete.tar.gzStill no joy. The only plugins are filesystem_attachments 1.0 and jqueryui 1.12.0.
I can scroll through the folders using these OS, browser combinations:
Ubuntu 18.04.1, Firefox Quantum 62.0 (64-bit)
Windows 10, Google Chrome 69.0.3497.100 (Official Build) (64-bit)
Windows 10, Microsoft Edge 42.17134.1.0
And I can scroll though the subscribed folders when I read mail on all OS, browser combos, including the android tablet. But that doesn't help me manage which folders I subscribe to.
I'm attaching two screenshots:
roundcube-android-chrome-50.jpg - shows the problem page on android & chrome
roundcube-win10-chrome.png - shows there are many more folders I can get to on windows 10 & chrome
Roundcube is on my personal web server. I've got full access and I'm also a software developer, although I've only tinkered with php. I can certainly apply and test patches, submit pull requests on github, and maybe do some coding. Please let me know how I can help improve roundcube.
