I really need to get everything transferred over to CVS.
Maybe it's different where you live but here I would simply need to tell my doctor "hey actually I want to use CVS now. Can you send the prescriptions to CVS at the corner of X and Y Street? Thanks"
Then when you get to CVS you'll need to give them your ID, phone number, signature, etc. and they'll fill your script and that's your new pharmacy. You can also use multiple pharmacies (I use Walgreens for one script and Kroger for the rest). If your doctor is disorganized with their notes and sends it to Rite Aid next time, just call CVS and tell them you want to get them transferred and they will call them and handle it for you.
HOWEVER
There is a MASSIVE strike of pharmacy workers across the country now. Mainly CVS and Walgreens but I asked my (local branded) Kroger pharmacy tech yesterday when I picked up a prescription if it's affecting them and she said yeah they're short staffed and she's never seen the pharmacist so busy. So it's likely to be affecting all pharmacies for the next few weeks as they play catch up.
This is only a couple weeks after 75,000 Kaiser employees went on strike which makes me think it's an industry-wide issue and we'll see more issues in the near future. Support your local pharmacy people, if you still have one.
Also
Plugging GoodRx here. If you don't have drug insurance or your drug isn't covered,, they're a massively helpful cost-saving company. You just type in the drug name and dose and the pharmacist enters it like regular insurance. They save me a couple hundred each month.
I'm not sure if it's an Android feature or Samsung feature, but try hitting the sideways hamburger menu (3 vertical lines button that's always on the bottom} and then holding your finger on the app you want to half screen. See if you notice anything happen... if not it's a Samsung thing.
