### 1/5 — Boring

*2020-12-20*

So far I have found this AdventCalendar to be totally boring and have no connection with Christmas what so ever besides the front picture, which I find extremely hard to even see the numbers on. 
I have persisted in the hopes sometimes amazing happens on the 24th but I am doubtful. 
I won’t be installing this next year

### 1/5 — Having trouble deleting this app

*2019-12-07*

Every time I restart the phone or shut the phone off, this app stays there as if its downloading and it should be gone because I’m low on storage. How do I fix this?

### 1/5 — Just a disguise for ads
