After trial I’m DONE.

So my first trial was horrible. The community share didnt work. They extend my trial and my poshmark app is not sync with sidekick app. The customer service is lacking. I joined the discord community. Someone spoke and then I was removed. Thats ok. Im done after trial. This app needs alot of work. Too many glitches.

Phone invalid

Why ask for phone number if it’s going to say phone number not valid. Dude remove that phone # section because I used my personal and business number and it says they are both invalid and they are both legit numbers I’ve had for years.
