I have had this problem for a few months now. When someone sends text or voice messages, I get them on the lock screen just fine. However, when it’s a sticker or a photo, I don’t receive anything on the lock screen. I can only see them inside the app.
I should also note that sometimes I do receive notifications on the lock screen for photos or stickers, but it’s rare.
أبغى طبعة لديوان الحماسة كويسة وفيها شرح، سمعت عن طبعة دار المعارف ودار صادر لكن ايش الأفضل؟
ما عمري فهمت، كيف مثلًا البصائر والذخائر كتاب من ٦-١٠ مجلدات ولكن في مثل هذا اللي في الصورة، كتاب واحد؟ يعني هذي مختارات ولا ايش؟
I got the answer without adding the second part, and when I added it I got a wrong answer, how is that?
أبحث عن كتاب يشرح علم العروض والتقطيع العروضي وكل ما يتعلق به دون تعقيد؛ فيكون بمثابة تأسيس ابتدائي ثم أقراء ما هو أكثر تفصيلًا.
أسمع كثييير عن دار صادر لكن مو متأكدة لو طبعاتهم كويسة لكل الدواوين
..أبغى أشتري كم ديوان اونلاين فما أعرف كيف بتكون الجودة
من أهمها: الحماسة لأبي تمام، ديوان أحمد شوقي، ونقائض جرير والفرزدق
يفضل يكون نفس دار النشر، لكن لو في ديوان معين له نسخة أفضل بدار نشر غير الباقيين عادي أنوع برضو

I 17f went to the dermatologist to get a deep cleansing facial because I have really stubborn blackheads that are not affected by all the cleansing masks and creams and such. She said that the blackheads were deep in the skin, and that my skin is very dry, and so I would need Mesotherapy..
I know she’s the doctor and all, but I’ve never heard anyone say that Mesotherapy could be necessary. I thought it was just an extra cosmetic procedure and not a treatment of some sort.
When I refused, she said my skin could breakout after the blackhead removal since they are deep and she needs to compensate the space they’ll leave apparently. Has that happened to anyone?
Wasn't the solution to a positive square root always positive and negative?
Like square root of 4 = positive or negative 2 ???
I tried to solve this question in two ways I know are correct, but only the first one(photo 1) worked for some reason. I can't figure out why the second is wrong?
Can someone explain the difference? Which is used on the SAT?? Does the trial’s difficulty affect either?
Every trial I see a lot of students on here talking about it, but I still don’t get the difference..
Why is the median the value of the 88th number and not the 87th? I know the answer won't differ in this case, but what if it does in another question?
Why did we divide by the number of students and not the number of pets? It's asking about the pets right? How can I know which sum I'm supposed to divide by when given a table like this?
