This webpage does not recognize uppercase and lowercase English characters, so it is slightly modified. In order to gather some luck, I will share you the difference between the two statuses (Under review and Under Review) after the submission of IoT Journal. The lowercase “review” indicates that the article is under external review, and the uppercase “Review” indicates that AE or the editorial office can handle the article at this period. Therefore, your article shows Under Review when you first submit it, and it will become Under review after the actual external review starts (It takes a long time for the IoT editorial office to assign AE, and it is estimated that the status will change after three weeks). If it changes to Under Review after a while, the high probability of triggering this change is that the time for reviewers that given by AE is up, and not all the reviewers have yet submitted their comments, but the number of submitted comments can theoretically be enough for AE to make a decision, that is, no less than two reviewers sent back their comments. For reference only, everyone can also verify it.

Given the opportunity to make changes, and still saying the theme is not relevant?

This journal is really problematic now. After 7 months, the first-round revision was rejected, with the reason being that it did not meet the scope. It's really outrageous.

(0) Thank | W81350

After major revisions, there are minor revisions, followed by more minor revisions. The reviewer is really tough, never finishing with just one issue...?

(0) Thank | C& AGWAII

Does experiencing three R's and three r's belong to this situation? I should be on my third r now.

(0) Thank | GuoZiZhu

Two to three will become Big R, but if four are invited at the beginning, it will once again become small r waiting for the opinions of the remaining reviewers.

The submission was made in the new system, and it has been over a month since the submission was made. It is still in the second round of revisions, and it seems like it has not been sent for review yet.

(0) Thank | fengk

Did you submit in the new system? I have submitted for two months already, but haven't heard anything yet.

Does anyone know why, after receiving several review comments, the font size becomes large "R", and then becomes small "r" again? I wonder if it's because of inconsistent opinions or insufficient quantity.

It seems that my work is still in the hands of AE and has not been submitted for review.

(0) Thank | yyy1019

The two small "r"s turning into a capital "R" means that it has been reviewed and we are waiting for the final decision from AE.

Hello, is little r the one for external review? I resubmitted on April 18th, and there was a day when it changed to little r, but then it has been big R ever since. Does this mean it has not been submitted for review yet?

(0) Thank | yyy1019

I also asked, still Under Review, feeling overwhelmed, the "r" in the middle has shrunk twice.

(0) Thank | CCSI0761

Why is it so fast? I returned it for repair on March 14th, and it is still Under Review. It clearly went under review twice.

(0) Thank | CCSI0761

The change was too fast to catch, thank the editor and reviewers, 4.27 minor.
