[LaurenWags]

Description

Found while testing #4224

After following the STR in above issue and updating to 0.64.74, the Ads panel no longer showed the incorrect error message but I did not receive a notification to try Ads.

Steps to Reproduce

Scenario 1:

1. Install an older build say (0.58.21)
2. Enable Rewards. ensure ads is not available
3. Upgrade to 0.63.48 or 0.63.55
4. Ads shows sorry not available for your region even if the criteria matches
5. Update to 0.64.74
6. Ads panel shows toggle (you can enable Ads) but there is no notification alerting you to try ads.

Scenario 2:

1. Install an older build say (0.58.21)
2. Enable Rewards. ensure ads is not available
3. Update to 0.64.74 directly (skipping 0.63.x versions)
4. Ads panel shows toggle (you can enable Ads) but there is no notification alerting you to try ads.

Actual result:

No notification to alert the user that Ads are now available.

Expected result:

Notification to try Ads is shown on BAT logo.
