PIP Review SMS

Hi,

I have received an SMS from DWP stating:

“ Your PIP review is complete. You should receive your decision letter in 2 weeks. Once you receive your letter, contact us if you have any questions. Do not call before you get the letter as we will not be able to tell you the decision. Please remember to contact us if your circumstances change.”

I have not had a medical assessment or any contact from DWP other than interim SMS messages saying they are still reviewing my claim.

Should I be worried or relieved or both?

Can they stop an award if they have done a paper based assessment, or does it mean my award will continue?

I have this morning received the same SMS. I had a letter saying my award was extended until 8th July. I called the PIP line this morning and it says my next payment is 29th July and is for the same amount as it usually is. If my claim was declined, would it end on the day of the decision, meaning I wouldn't get the next payment on 29th? I'm trying to preempt the decision letter, as I am now on holiday for 2 weeks.
Thank you in advance.
