The Professional Edition of the iOS App supports a selection of macro functions of the desktop edition for Windows and Mac.

Macro functions are created in the PhraseExpress desktop client. You can’t create macros on the mobile device.

Don't panic! It is unlikely, that phrases are lost (unless you uninstalled the App and confirmed to delete all associated data).

If using iCloud Drive, open the Apple "Files" App and open the folder labelled "PhraseExpress".

Does the file show a cloud tag with an arrow-down icon? Then tap the file "phrases.pxi" to trigger downloading the phrase file from your cloud account to your device.

Then close and relaunch the PhraseExpress App.

Hope this helps.
