**System Information:**
- **OS:** Fedora 42
- **RetroArch Version:** 1.21 (Flatpak, updated April 29, 2025)

### **Issue Description:**
The **"Import Content"** option remains missing/unusable despite following standard troubleshooting steps. Below are the **6 attempted fixes**, none of which resolved the issue.

---

### **Attempted Solutions (All Failed):**

#### **1️⃣ Checked Default and Alternate Locations**
- Looked for `Import Content` in:
- `Main Menu → Playlists → Import Content` (not present)
- Enabled `Show 'Import Content'` in:
**`Settings → User Interface → Menu Item Visibility`** (no effect)

#### **2️⃣ Updated RetroArch**
- Ran:
```bash
flatpak update org.libretro.RetroArch
```
- Confirmed version **1.21** is up-to-date.

#### **3️⃣ Granted Filesystem Access via Flatpak CLI**
- Explicitly allowed access to ROMs directory:
```bash
flatpak override org.libretro.RetroArch --filesystem=~/Games/ROMs
```
*(Path verified to exist and contain valid files.)*

#### **4️⃣ Inspected `retroarch.cfg`**
- Checked `content_directory` in:
```bash
~/.var/app/org.libretro.RetroArch/config/retroarch/retroarch.cfg
```
- Variable not present.

#### **5️⃣ Reset RetroArch Configuration**
- Backed up and reset configs:
```bash
mv ~/.var/app/org.libretro.RetroArch/config/retroarch ~/.var/app/org.libretro.RetroArch/config/retroarch.bak
```
- **Result:** Fresh configs did **not** restore the option.

#### **6️⃣ Used Flatseal for Full Permissions**
- Granted **all possible permissions** via Flatseal:
- ☑️ **Filesystem:** `All system files`
- ☑️ **Libraries:** `Full access`
- ☑️ **System Configuration:** `Enabled`
- **Outcome:** No change in UI or functionality.
