## Most critical reviews (8 lowest-rated)

### 1/5 — Horrible Customer Support

*2026-03-09*

They do not care about the mobile app and if you want to use IPC documents your at their mercy. 
Would think a company that supports 100,000+ customers worldwide does not care about its own image.
Can’t wait until a new solution comes out to get paired with IPC so their workflow can actually be usable in this century.

### 1/5 — Worthless

*2026-02-06*

Only open one page at a time by selecting bubble.  No means to scroll from page to page.

### 1/5 — Can’t Open Anymore

*2025-07-30*

This app worked fine for the first 6 months I had it. Then all of a sudden, I can no longer open my File. I tried contacting their support team, but to no avail. Unfortunately, you can’t call them, but have to File a Ticket, thereby making it easy to ignore, which they have done now for over a week when promising a 24 hour response time.

### 1/5 — Couldn’t open the file

*2024-11-04*

Prompt “Error contacting Permission Server”. Please help update the app to be used in the newer version for iPad OS….

### 1/5 — Basically impossible to open something

*2024-05-08*

Not able to open files as there is nowhere to do it

### 1/5 — Hopeless - defeats the point of a portable app

*2023-05-10, version 1.0.5*

Needs internet access to open files - unable to check files when outside 4G range or inside tunnels.

Annotations are NOT possible.

Viewing settings will default on every re-open of the same app.

Pointless app and very limiting licensing.

### 2/5 — Crucial functionality missing

*2024-04-28*

It opens the files as expected but the ability to actually work with documents is heavily reduced without any markup features (e.g. highlighter and underline in different colours, comment). The addition of those would be highly appreciated.

### 5/5 — Very fast!

*2023-07-30, version 1.0.5*

Love the new update! Super fast!
