I use one of the best latex editing apps on iPadOS/iOS called Texpad. Although the app itself supports Dropbox, the issue is that Dropbox's poor integration with the Files app on iPadOS/iOS 13 makes it impossible to import and work on multi-file projects that require folder level access to Dropbox. Furthermore, file names sent to the Files app internally are case insensitive and hence it screws up with basic file syncing. The Texpad developers have told me that they are willing to improve Dropbox support, if only Dropbox fixes these glaring issues and conforms to the file sharing standards of iOS 13 just like iCloud, Working Copy (an iOS git client) and Documents (by Readdle) have already done. Can we see better file sharing support on iPadOS/iOS in future Dropbox updates?
