### 1/5 — Scam

*2026-03-20*

Purchase does not unlock the useful part

### 1/5 — Pro Version Issue

*2026-03-16*

I purchased pro version but hidden symbols still do not appear and no response from vendor and no fix.

### 3/5 — Works well. Major issue.

*2026-03-01*

I purchased pro and cannot add the hidden categories to the keyboard. Only the initial three are available. I have not been able to try the part of the app that it is most useful for due to this. I have “Full Access” enabled.
