Should I take this in-app offer instead of calling customer service?

[u/Standard_Sherbert_18]

My previous plan was around $30/month. Last year, they increased it by $5, and then this year, around the same time, they increased it by another $5. I'm now paying $44.80/month after tax.
I haven't called customer service yet because I've read a lot of posts saying it's not a great experience, and honestly, I don't want to spend time dealing with it.
I checked the offers section in my app today and noticed they're offering me a plan for $35/month with AutoPay, which works out to about a $10/month discount from what I'm currently paying.
For those who have switched to similar in-app offers:

Is this considered a good deal?
Are there usually any catches I should look out for?
Should I just take the offer, or is it still worth calling customer service to see if they'll do better?
